Add installation instructions

[brombomb]

I would love to get this up and running even if it's early. I'm a bit green in the python dev world so I'm not sure the best way to get up and running with pip vs poetry.

Thanks!

This project is setup using poetry and poetry definitely makes using this simpler for newbies. Install poetry, run poetry install
There are tests for running the library specifically 2 one uses the older codebase test_instance.py and one uses the newer codebase (same for HA integration) test2_instance.py

Run them with poetry run python3 tests/test_instance.py

I'll update the wiki today.
