refactor: Cleaned pyroengine and refactored project

[frgfm]

This PR introduces the following changes:

• simplified pyroengine
  • deprecates pi_utils (not used)
  • moved pyroengine.engine.engine to pyroengine.core
  • added pyroengine.vision with Classifier which holds the ONNX model
• updated tests
  • moved "test" to "tests"
  • switched from unittests to pytest to harmonize our test suite across repos
  • added exhaustive unit tests for pyroengine (only part not being tested : API interactions, because it requires to run it locally)
• updated docs
  • updated documentation theme from rtd_theme to furo (cf. modifications in pyrovision)
• deleted server folder
• renamed runner as src
• cleaned src by implementing ReolinkCamera and SystemController
• refactored all requirements.txt and config files into pyproject.toml
• added a Makefile
• updated CI jobs accordingly
• updated docker file accordingly

Basically, for the wrapper (orginially runner, now src), the only difference is:

• previously, we needed the following keys: "model_weights"
• now, we need: "cfg_path" (describing the preprocessing), "model_path" (path to ONNX model), "hub_repo" (fallback to download the model from HF hub)

For reviewers, I highly suggest to check the modifications by commit, it might be easier 😅

Hi @fg, thanks so much for this PR! Globally LGTM. Several sticking points though:

1. This PR must be merge on develop and not main directly
2. CIs must run on main & develop

To discuss

We never used the felix code to monitor the pi's but I think it would be nice to do so, I don't know if it's a good idea to delete it

NB: It would be better to use a fork

All good, codebase should be clean :)

Thanks for the update, what about these comments ?

Oops I didnt see the last part:

• I removed it because it comes with dependencies (I would have kept it otherwise)
• thought it would be better to start with a clean environment, then add it back later and see how we integrate it
