feat: monitoring tool first version

[chrismclarke]

Description

Proof-of-concept to show potential support of using ODK forms directly in the app.
This is a huge addition, as to do so involved directly copying and the current odk/enketo codebase and rebuilding it as the existing version is somewhat limited for using in an offline-first way.

This PR successfully creates a standalone picsa-monitoring tool, which is then embedded within the picsa extension app. This tool allows the selection of an odk form from a list, and displays the form entirely offline with full access to the form available from the app.

The PR does not add support for saving or editing form submissions, as that is a considerably large next piece of work (tracked in #55 )

Discussion

• Do we have any existing forms we want to test integrating?
• It would be good to discuss options for where/how to store survey responses. The options would be either to use kobocollect or our own database.

Preview

Released as version 3.13.0
