Update Makefile and Readme with new development experience

[nateinaction]

Summary

This PR updates the Makefile with new targets to help developers.

Running make takes the place of all of our setup instructions. It will setup the venv, download all dependencies, install the pre-commit hook.

You can also deploy to the board just by running make install

make help displays more of what you can do!

make help

Usage:
  make <target>
  help             Display this help.

  download-libraries  Download the required libraries
  fmt              Lint and format files
  test             Run tests
  install          Install the project onto a connected PROVES Kit use `BOARD_MOUNT_POINT` to specify the mount point
  clean           Remove all gitignored files such as downloaded libraries and artifacts
