[libcamera-devel] [libcamera-devel 2/5] ipa: libipa: Add init() function to the Algorithm class

[Florian Sylvestre]

Add the init() function that will be called during algorithm initialization
to provide each algorithm the list of algorithms tuning data.
Each algorithm will be responsible to grab their corresponding parameters.
