From: Abhradeep Chakraborty <chakrabortyabhradeep79@gmail.com>
Bitmap file has a trailing checksum at the end of the file. However there is no information in the bitmap-format documentation about it.
Add a trailer section to include the trailing checksum info in the `Documentation/technical/bitmap-format.txt` file.
