Add on_progress callback for transcribe and align

[stex]

This adds an optional on_progress argument to both the align and transcribe methods.

This allows processing the current progress via a callback, until now, it was only possible to print the progress to STDOUT.

Example:

transcribe(
  my_audio,
  batch_size=8,
  on_progress=lambda state, current=0, total=0: print(f"state: {state}, current: {current}, t: {total}")
)

States are defined as

class TranscriptionState(Enum):
  LOADING_AUDIO = "loading_audio"
  GENERATING_VAD_SEGMENTS = "generating_vad_segments"
  TRANSCRIBING = "transcribing"
  FINISHED = "finished"

this feature is exactly what we need at the moment

@matheusbach @IgorTavcar is there something missing in this PR that you'd need for your work?
I removed the "draft" state, so it's now up to @m-bain

I appreciate if it the function parameter was padronized between transcribe and align step. Also, the enumerated status used in transcribe step is very useful
