Transcripts in Overcast!

This was so much work. I can't believe I've finally gotten it into beta.

@marcoarment just checked it out, it looks awesome! Just like captions, you don’t know how useful they are until you use them for a bit, this is a huge accessibility win for Overcast. Nice work!
@marcoarment do you like TestFlight feedback? I just sent one, local transcription seems bad with the upload feature with audio files that are 15+ hours long, it basically makes your phone melt and never seems to finish. Maybe it could cap the length it attempts to something the phone can accomplish?
