Remove dependency on custom pylibcamera fork #3
Description
Reinitialising the camera to load a new lens shading table (i.e. update the tuning) only works thanks to a hack in pylibcamera. This i inelegant to say the least! I've also had limited success building the modified library, and currently it relies on cross-compiling or it won't finish.
It would be nice to revisit the code to figure out why it's not correctly reinitialising: I think there's a reference not being correctly disposed of, but I have yet to figure out where it is. Sorting this out and submitting any required upstream fixes would be an extremely helpful thing to do, but isn't currently urgent enough for me to spare time for.
