[PATCH 0/3] ipa: simple: Introduce metadata reporting

[Kieran Bingham]

Provide metadata reporting for the SoftISP. Initially the Black Levels
and ColourGains are reported, but also serve as a direction to add
further metadata or internal reporting of the softisp.

Running cam -c1 -C10 --metadata now produces the following:

1668.359684 (14.95 fps) cam0-stream0 seq: 000004 bytesused: 15069888
	SensorBlackLevels = [ 20, 20, 20, 20 ]
	ColourGains = [ 0.316406, 0.299805 ]
	SensorTimestamp = 1668359684000
