[libcamera-devel] [PATCH v2 09/11] utils: tuning: Add alsc-only libtuning raspberrypi tuning script

[Paul Elder]

Add a tuning script for raspberrypi for alsc only, that uses libtuning.
Since there will also be a tuning script for raspberrypi that has more
modules, put the libtuning alsc module definition in a separate file so
that it can be reused later.

Changes in v2:
- fix python errors
- fix style
- add SPDX and copyright
- s/average_functions/average/
- update script to work with new raspberrypi alsc module
