5e65f24aea extract-partitions.py: allow for disabling --max-size 
Useful if you want to dump everything. For finer selection, use
partitions.py directly.

a27775129d extract-partitions.py: fix reading 512 bytes too short 
/proc/partitions outputs blocks of 1 KiB, but the size can be aligned
at 512 bytes (as observed with the "grow" partition). Re-use the
partitions.py code for dumping partitions.

Previously every partition would be opened separately, now this
requests the partition offset and size for each partition, but the disk
is opened only once.

This takes about 32 seconds for 356 MiB.
