Changelog:
- Added current limit getter/setter functionality
- Because this is different for various of the TIC controllers, classes for each should be made to account for differences
This is a breaking change, as these new classes are the ones that should be instanced from this point on.
To use in CircuitPython, simply install the [CircuitPython Community Bundle](https://circuitpython.org/libraries).
