Move dump_pocketbook_update.py into a separate repo and make it a python package
Add 0x76 as another header for uboot
I have encountered an image where 2 part_headers for uboot are present with the same contents and hash, one with 0x75 part type, and another one with 0x76.
`dump_pocketbook_update.py` and `pocketbook_update.ksy` fail on recent PocketBook firmware (fixed by PR #4 )
