- `accepted_value` now in individual scope classes - to be removed in v0.2.0
- new formats for `scope.get_waveform`: `default` returns a <bytearray> - `list` returns a <python_list> of exactly the bytearray data, and `np_array` returns a numpy array with bytes being interpreted from the `waveform.data_width` property. The list will have the proper integers.
- the MSO54 scope class has been mostly implemented
