Enhanced mmu 3.0.0 support.

[jukebox42]

Octoprint-PrusaMmu.zip Enhanced the MMU 3.0.0 support with some needed fixes. Also now reports the error from the printer on the settings menu.

New Features:

• Reports the printer error in the header AND shows more details in the settings menu

Bug Fixes:

• Should now clear error in header when printer resets
• Better detects specific events so the header should get stuck less overall
• Fixed the duplicate event spamming

Internals:

• Copied the MMU error yaml. I had to comment a few out because they share hex codes. Future versions can probably fix this
• Added file with printer commands to make testing with virtual printer easier
• Added a few more checks to MMU state codes
  • INIT="MMU2:<X[0-4] F" - Notification that the MMU is done starting up. This gets spammed a lot
  • VERSION="MMU2<S3 A" - fires when printer/mmu restarts
  • ERROR="MMU2:<(?:[^E]) (E[^]*)" - format for an error message
• Added a LIVE_STATE to reduce the event spam because of how noisy 3.0.0 is. LIVE_STATE is synchronous, STATE is asynchronous
