prior to this, the concatenate assumed it was concatenating a firmware
with a full *storage section*, e.g. the already-padded 8192 bytes, but
it's equally valuable now that I'm creating configs to have just a
config section + footer, which needs to be padded 8192. now concatenate
supports both
now you don't need to fiddle with specific byte ranges of a dump, you
can just dump the whole board if that's more convenient, and
visualize-storage will parse that
also more testing in general
