make the python decoder compatible with Sinter

[NoureldinYosri]

Sinter is stim's way of unifying the API of different decoders. it would be nice if Tesseract's python interface implements the same API.

example from Chromobius Decoder https://github.com/quantumlib/chromobius/blob/35e289570fdc1d71e73582e1fd4e0c8e29298ef5/src/chromobius/pybind/sinter_compat.pybind.cc#L79
