Detect miniscopes

[sneakers-the-rat]

We need some means of detecting and identifying connected miniscopes and returning the appropriate reader class for them.

Something like

scopes = detect_miniscopes() # type: list[MiniscopeIO]
scope = get_miniscope(id="some-id") # type: MiniscopeIO

To do this we need to

• [ ] design a header that reports miniscope identity, hardware version, any applicable config, and firmware version
• [ ] implement a registry in miniscope firmwares that reports the header
  • [ ] ... which firmwares need to be updated?
• [ ] make generic reading functions for querying
  • [ ] I2c
  • [ ] serial
• [ ] implement reading classes with class attrs ti match them to firmware header values
• [ ] make wrapper function for querying devices and returning the matching, instantiated class
