Substantially reduced time required to verify program memory contents.
Now verification consists of dumping program (i.e. flash) memory
in a block from first address in given hex file to last non-config
address in given hex file and then comparing given values with read
values. As before, quits upon first mismatch found.
Relatedly, code to perform a program memory dump has been moved to
a dedicated function, dump_pm.
