Circuitpython-cirque-pinnacle

Like the last release (except I fixed setup.py), this release is mostly documentation improvements.

Although, there are some code improvements too:
- `measure_adc()` still exists, but its algorithm has been exposed as `start_measure_adc()` & `get_measure_adc()` for asynchronous applications.
- re-proritized parameters' order to `relative_mode_config()`
- changed examples to demonstrate proper namespacing as previous examples may have been confusing to newcomers in python

This pre-release is meant to test GitHub actions deploying to pypi
