skip padding metadata blocks

Drafted. ~Working only if modded  as:

- skipsize = framesize;
+ skipsize = framesize - map.size;

As it is, it seems to fail to find any valid data after
the skip. Still working on it, maybe I'm over-skipping or
failing to set the parsing state accordingly (maybe it's
the last metadata block?).  Should be enough to confirm
the approach is correct though. All comments welcome ;)
