Also some improvements with stability eg sending initialization data on startup, although there are still some unresolved issues by users (https://github.com/strodgers/epomaker-controller/issues/29)

There were lots of dependencies on this project that are not needed

I have removed most of them and separated out test requirements

- Add option to generate udev rule for keyboard, avoiding need to run as root

- Fix issue with upload-image, should use interface 0
- Support multiple PIDs as reported by users in https://github.com/strodgers/epomaker-controller/issues/17
- Minor updates to daemon

Basic functionality to communicate with the Epomaker RT100 keyboard over USB:
- Send numbers to the CPU and temp displays on the screen
- Send an image to the screen
- Update time/date on the screen
- Start a daemon to send CPU usage and/or temperature information to the screen
- Basic RGB controls, cycling through available profiles, setting all keys to one colour

Problems:
- No support for 2.4Ghz or Bluetooth
- Some users reporting problems with HID interface numbers (https://github.com/strodgers/epomaker-controller/issues/17)
- Need better support for using the actual keyboard eg macros, setting individual keys via CLI, layers
