BakingTray, the project this code was originally spawned from. They have not
been tested on hardware and should be reviewed before release.

Replace the legacy serial()/fopen/fgets transport with MATLAB's serialport
interface and the async command-queue approach developed on the BakingTray
laser_power_bug branch. This fixes the button-press-vs-poll serial collisions
that dropped commands, and modernises the deprecated serial() dependency.

Laser side (issue #16):
- New laserControl.asyncSerial mixin: single command queue, one terminator
  callback, fire-and-forget enqueueRead for background polling, and a stale
  in-flight watchdog. Uses fprintf for logging (no loghandler dependency).
- laser base class now inherits asyncSerial and owns a background status
  poller (pollSerial), a faster tuning poller, pause/resume gating so commands
  never interleave with a poll, and emissionPossible. Adds observable
  currentPower_mW / currentPumpPower_mW. Pockels/beamName (BakingTray-only)
  dropped; hAOM and the GUI observable set retained.
- chameleon and maitai rewritten onto serialport + asyncSerial with per-query
  reply handlers driven from the poll queue.

AOM side:
- MPDSaom moved onto serialport with synchronous reads (the AOM is command/
  response driven by the wavelength listener, not background-polled, so it does
  not route through the async callback). connect/delete/sendAndReceiveSerial/
  nonStandardSerial/reset updated; the '?'-terminated status read is
  reproduced so the existing regex parsers are unchanged.

Dummy laser (issue #14):
- Defaults to powered-on with the shutter open and tunes instantly; set
  simulateSlowTuning=true to restore the gradual wavelength ramp.

GUI:
- laser_view / aom_view updated to serialport-safe buffer checks
  (NumBytesAvailable / flush) guarded for the dummy laser's empty port.

Untested on hardware. The MPDSaom nonStandardSerial trim offsets and the
serialport reply framing should be checked against a real MPDS driver and a
real Chameleon/MaiTai before release.

The laser class now publishes its state through SetObservable properties and
runs its own background serial poller, so the GUI no longer needs to poll the
hardware. laser_view is now purely reactive:

- Removed the GUI's two timers (currentWavelengthTimer, laserViewUpdateTimer)
  and their callbacks (updateCurrentWavelength, regularGUIupdater).
- Each element repaint is driven by a PostSet listener on the matching
  observable (isLaserOn, isLaserShutterOpen, isLaserConnected,
  isLaserModeLocked, currentPower_mW, currentWavelength, targetWavelength).
- The element updaters and button callbacks now read the cached observable
  properties instead of issuing serial reads (isShutterOpen/isModeLocked/
  readPower/isPoweredOn). A single readWavelength at construction seeds the
  display; the poller keeps it fresh thereafter.
- laser_view_si_hooked pauses/resumes the laser's background poller during a
  ScanImage acquisition (previously it stopped the GUI timer), which is the
  real "disable laser updating during scan" behaviour now that the GUI is
  passive. No-op for lasers without a poller (e.g. the dummy laser).
