This contains Rust wrappers around enough of the Python API to implement Rust versions of the `battery_client` and `run_scanner` examples. The goal is to gather feedback on the approach, and of course to show that it is possible.
The module structure mirrors that of the Python. The Rust API is not optimally Rust-y, but given the constraints of everything having to delegate to Python, it's at least usable.
Notably, this does not yet solve the packaging problem: users must have an appropriate virtualenv, libpython, etc. [PyOxidizer](https://github.com/indygreg/PyOxidizer) may be a viable path there.
a. `DeprecationWarning: The 'warn' method is deprecated, use 'warning' instead`
Updated call in `bumble/smp.py`
b. `ModuleNotFoundError: No module named 'bumble.apps'`
Updated imports in `tests/import_test.py`
c. Added `pytest-html` for easier viewing of test results
Added package in `setup.cfg`, and hook in `tasks.py`
d. Updated workflows to use `invoke test`
This is a partial fix of #81
