chore!: combine into single media-stream-library package

Moves the overlay, player, and streams modules into the media-stream-library
package, but as separate exports. This simplifies package management and
moves the two smaller related packages into the main package.

Improves to the way releases work:
- Always have the package version changed when any changes are made
  to the source, and add a verification for this (housekeeping job).
- Release using a workflow trigger, takes the package as it is and
  creates both a GitHub release and publishes to NPM, using the version
  already contained in the source.
- Keep the minified bundle that includes the dependencies outside of
  the dist folder (thereby excluding it from the NPM package). Since
  that bundle is only needed outside of a package system, and then
  we don't need to export it separately.

BREAKING CHANGES:
- `media-overlay-library` and `media-stream-player` packages are no longer
  provided, they are now available from `media-stream-library/overlay` and
  `media-stream-library/player` respectively.
- The format of the minified bundles is changed from IIFE to ES module,
  since this now has baseline support across all modern browsers.

Together these changes allow for simple release flow, where we can
just pick latest main for releases, where the correct version is
already part of source control.

+## 14.0.0-beta.0
+
+- Switched to workflow-based releases with version as part of source.
+  This means that each PR has to have an update of the package.json version
+  number and update the CHANGELOG.md file.
+- **BREAKING**: Move `player` and `overlay` packages into the `media-stream-library` package.
+  These can be imported as `media-stream-library/player` and `media-stream-library/overlay`.
+- **BREAKING**: Only export ES modules (including minified bundles with external dependencies).
+- **BREAKING**: Replaced Node.js Buffer with Uint8Array.
+- **BREAKING**: Replaced Node.js Stream module with Web Streams API.
+  Components and pipelines are redesigned completely, check the source
+  and examples for details on how to migrate.
+- **BREAKING**: Replaced `debug` package with internal log module.
+  Set `msl-streams-debug`, `msl-player-debug`, and `msl-overlay-debug`
+  `localStorage` keys to `"true"` instead for logging.
+- **BREAKING**: Removed CommonJS support and separation of Node.js
+  and Browser exports.
+- Added AAC test audio to the default RTSP H.264 test video.

+```
+
+or
+
+```sh

+
+## Contributing
 
 For development, you'll need a local installation of [Node.js](https://nodejs.org/),
 and [yarn](https://v3.yarnpkg.com/) to install dependencies.
 To run commands, you need [just](https://just.systems/), which can be installed using
 [prebuilt binaries](https://just.systems/man/en/chapter_5.html#pre-built-binaries) or
 [yarn](https://just.systems/man/en/chapter_8.html#nodejs-installation), e.g.
 `yarn global add just-install`.
+
+Please read our [contributing guidelines](CONTRIBUTING.md) before making pull
+requests.
+
+## FAQ
+
+**Will it work with this library if it works with VLC?**
+
+Not necessarily. We only support a particular subset of the protocol useful for
+basic streaming from IP cameras. With RTSP that is H.264+AAC or JPEG, and only
+some simple profiles/levels are supported. For MP4, it depends entirely on your
+browser if the media can be played.
+
+**Do I need to use RTSP for live (or low-latency) video?**
+
+Since this library only supports RTSP through some form of TCP connection, it's
+going to have similar latency as streaming MP4 over HTTP. For true low-latency
+real-time usage, you should either use a stand-alone player that can handle RTP over UDP,
+or use WebRTC in the browser.
+
+You should expect in-browser latency of several frames. When using Firefox, you
+might need to set the duration of the MediaSource to `0` to force live behaviour
+with lower latency (see one of the browser examples).
+The exact latency is controlled by the browser itself, and the data inside the
+media stream can affect this (e.g. if audio is present or not).
+
+**Does this library support audio?**
+
+Yes, yes it does. With a few caveats though.
+
+- Make sure your AXIS camera actually supports audio
+- Make sure the audio is enabled on the camera.
+- It only works with H.264 and only after user interaction with the volume slider
+
+**How do I autoplay video?**
+
+Browsers will only allow to autoplay a video if it's muted. If the video is
+not muted, then it will only play if the `play` method was called from inside
+a handler of a user-initiated event. Note that different browsers can have
+different behaviours. Read https://developer.chrome.com/blog/autoplay for more
+details.
