Support linux

[abrichr]

Implements support for Linux (#144)

Desktop application is not included.

Note that this requires X11. On Ubuntu 24.04:

1. sudo apt install xorg
2. Log out
3. At the login screen, click the gear icon or session selector next to your username. Xorg or a similar option.
4. Log in

Additional troubleshooting steps:

sudo apt install software-properties-common -y
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.10 python3.10-venv python3.10-dev
sudo apt install -y python3-poetry libportaudio2
poetry env use 3.10
# if poetry install hangs:
export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring 
python3 -m pip install -e .  # after poetry install
