ql: optimize USB data flowfixes
Write column data into a buffer, and only write
to USB once the buffer is filled past threshould.
This reduces the amount of data frames on the USB bus,
in a 429x336 sample image it was reduced from 1000 frames
to about 100 frames, where the image data is only 20 frames,
while the rest is mainly polling for status reponses.
