ipa: raspberrypi: Pass lineLength into the CamHelper API

Browse source 
Update CamHelper::exposureLines() and CamHelper::exposure() to take a
line length duration parameter for use in the exposure calculations.

For now, only use the minimum line length for all the calculations to
match the existing IPA behavior.
