Command line functionality

[psmsmets]

Move all functions from multi-ear-services.sh except install to a command line function in the pip package:

• multi-ear up(date)
• multi-ear conf(igure)
• multi-ear reset (or init, clear?)
• multi-ear debug
• multi-ear -help
• multi-ear -version

Make some of them accessible via the multi-ear-ctrl service.

multi-ear update

• Download release/branch from github to /tmp
• Uninstall prev version
• Install new version
• Restart multi-ear services

autoupdate:

• service that daily checks for release/branch updates
• Update should trigger a delayed update check (systemd timed service) after 15 or 30min, for example, as a safety precaution to catch errors in a release.

service that daily checks for release/branch updates

I would do this when the interface is loaded using #25. If a new version is available add a button that says "Update Now". I don't think a 15 - 30 timer is necessary to catch errors in a release. There should be no more errors when pushing to main. In the worst case there should be a "factory" reset option that brings the Multi-EAR back to the version it was tested/shipped? Can be done by checking out to a particular commit e.g.,:

git reset --hard 6e559cb

multi-ear update

Is using the .git in ~/Multi-Ear-Services not enough for the most part? A git pull followed by update should do the trick..
