rename Annotation.audio_path attribute to notated_path

[NickleDave]

as discussed in #120 #58

• rename to source_path
  • I kind of hate this name but I can't think of something more succinct and general
  • "source" is supposed to mean "the thing that is annotated"
  • another issue is that vak may rely on audio_path existing -- need to check this
• add spect_path
  • this is more intuitive naming
  • it actually could be useful to have both spect_path and audio_path attributes
  • but then this starts to make crowsettas job to be a dataset tracker, since for some reason it now knows there are both spectrograms and audio files; that's actually not what we want
  • another option would be to add a post_init that requires one of the two, but not both, to be declared, i.e. either audio_path or spect_path
  • but then this makes the job of generic-seq more complicated; does it track audio_path or spect_path? or both?

thought about the slightly cutesy notated_path

🤔

class Annotation
    annot_path
    notated_path

notated is not a word, or at least doesn't mean what annotated does.
But annot is not a word either.
At least it's more specific than "source" and avoids dealing with having multiple optional attributes

changed the issue name to reflect that
