Connect looks for /routes and /api/v2/streams/snapshot
These are now present and working.
I've also hard coded the static files directory - fixing this
properly is a work in progress.
Currently only has fast_autofocus, and there
may be some work to do on timing, but it works :)
Getting timestamps from the camera rather than
time.time() would be ideal, but it would take some thought to tie that up with
the encoder.
I'm using a low-res stream, as it seems impossible to
turn the bitrate control of the MJPEG stream off,
at least within the picamera2 API.
