feat(users/flokli/ipu6-softisp): init

Browse source 
This code adds support for the ipu6 webcams via libcamera, based on the work in
https://copr.fedorainfracloud.org/coprs/jwrdegoede/ipu6-softisp/.

It's supposed to be included in your NixOS configuration imports.

Subject: [PATCH 18/25] libcamera: debayer_cpu: Add BGR888 output support
BGR888 is RGB888 with the red and blue pixels swapped, adjust
the debayering to swap the red and blue pixels in the bayer pattern
to add support for writing formats::BGR888.
