1.10.0-rc.4

Improvements

• ( #503 ) Update label for enable_automatic_mode_switching to better reflect the behavior it introduces. Add a warning that it is incompatible with color commands.
• Publish device metadata along with HomeAssistant discovery configs. This will enable better removal behavior in the future.
• ( #499 ) Add support for hex colors (e.g., #FF0000) in color fields. Also add a hex_color field type, which publishes the color in hex format.
• Add top-level documentation for transitions in README.
• Change status: ON transition behavior: will always transition from brightness = 0, rather than last known brightness. I expect this behavior to be what most people expect.
