Fast Ctc Decode Versions Save

• PyPI (+py3.10) & NPM builds.

• add wasm builds.

• options for none collapsing repeats with CTC search functions.
• greedy, beam, & duplex search for CTC-CRF transitions posteriors probability outputs.
• all search method no longer hold the Python GIL so can benefit from Python multithreading.
• Python3.5 supported dropped; Python 3.9 builds added.

• 2D Beam search
• Viterbi search.
  • Optional phred quality scores.

• Support for multi-character labels (alphabet can now be any PySequence type).
• On encountering NaNs a RuntimeError is raised.

Performance improvements

Better handling on boundary conditions.

Better paths are produced over repeated labels.

Beam search now returns decoded path and sequence.
