pleorasrc: add support for IYU1 and IYU2 pixel formats

Browse Source 
This also needed a change to calculating the strides, as IYU1 is 12bpp,
and GstVideoInfo defines pixel stride in bytes, so for IYU2 the stride
was calculated as zero. Instead use Pleora's own definition of pixel
stride to calculate Pleora's row stride.
