Add basic hardware quality control assurance to workflow

[bruno-f-cruz]

This PR adds online QA routines for:

• Cameras

  • If a dropped frame is detected prior to session start, it will abort the session (usually a sign of high instability and something should be checked promptly)
  • If the trigger frame rate is not compatible with the exposure, an error will be raised
  • If a dropped frame OR trigger timing mismatch is detected during a session, a warning will be raised

• Harp Synchronization

  • if expected connected devices are defined - It will check with the white rabbit if all those pins are connected and raise an error if one is missing along with the name of the expected device
  • The heartbeat checks are waiting for the pico core devices to implement the latest spec

• Git repository

  • Check if the git repository is clean to ensure no experiments are run "dirty"

The checks can be disabled by setting the appropriate flags in the session model
