I'm now running stitching in subprocesses during the scan.
This seems to be working well - I'm using multiple CPU
cores and getting images out. However, the only way to
avoid circular dependencies was to combine the Things.
I'm still getting not-infrequent memory allocation errors from the camera, which may or may not be related.
This may not be in the codebase forever, but it's a very useful
sanity check to have during development.
The current implementation is clearly not a performance or
security risk.
`logging.basicConfig` doesn't work when run via `uvicorn`.
I now explicitly get the root logger and set its level to INFO,
which means we now see logs on the terminal.
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.
