ffmpeg needs to be installed

[stuartmaxwell]

Hi Simon - I believe this needs to have ffmpeg installed before this will work.

Before installing ffmpeg:

$ ospeak "Hello there"
/Users/stuart/.local/pipx/venvs/ospeak/lib/python3.11/site-packages/pydub/utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
  warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
/Users/stuart/.local/pipx/venvs/ospeak/lib/python3.11/site-packages/pydub/utils.py:198: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
  warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)

FileNotFoundError: [Errno 2] No such file or directory: 'ffprobe'

Then I installed ffmpeg: brew install ffmpeg

And the command worked perfectly. Probably just needs a note in the README file.

Thanks!

That's annoying - I got the impression from somewhere that adding simpleaudio as a dependency might mean ffmpeg wasn't necessary, but apparently not.

I'll update the README - thanks!
