Adding library file, examples (simpletest, fifo and one shot) and docs

👋 Thanks for this pull request! Unfortunately, it looks like the automated continuous integration (CI) test(s) failed. These can be tricky to fix so we've written a guide on how to fix them locally. It has pages about running pre-commit locally and another about building the docs locally with sphinx. Thanks for contributing to CircuitPython! If you have more questions, feel free to join the Adafruit Discord and post in #circuitpython-dev.

looks great, can you add some 'commented out' lines that show the different config settings? like the oversample, rate, etc
