Bottom line of frame is corrupted

[oskirby]

When the frame size (in bytes) is not a multiple of the DDR3 word size, then the final line of the image appears to be corrupted. This appears to be caused by a problem in the FPGA that causes the last block of memory to fail to be written. So far this has only been observed using the new timing program block, which would explain why we only see it in pychronos (the monolithic camApp builds still use the old timing block).

To reproduce the issue, set the camera resolution to 592x382, and the bottom right corner of the display should contain malformed pixels in the last row.
