Implements support for EzCad2/LMC protocol used by galvo-based laser systems (e.g. AtomStack M4).

Includes:

  • Protocol layer: All EzCad2 command constants, packet structures, list/single command management
  • Controller: List building, initialization sequence, laser parameter management
  • Encoder: Converts Ops commands to EzCad2 binary protocol with coordinate/power/speed conversion
  • Driver: Full Driver ABC implementation with mm->galvo coordinate conversion
  • Mock: MockGalvoConnection for testing without hardware
  • USB: GalvoUSBConnection via pyusb (VID 0x9588/0x9899 and VID 0x1A86/0x5512)
  • 106 tests: Controller, encoder, driver, and mock connection tests

Closes #261.
