This means a custom function in pff_diskio.c, disk_parsep(),
which replaces disk_readp(). Now it no longer reads a whole
sector for every single byte, but only once per line of G-code.
Performance is now much better than with buffered reading, the
1 MB file with 16'468 lines of comments, 64 bytes per line,
read and parses now in just 46 seconds, which means 358 lines
or 22'795 bytes per second.
Unfortunately all the binary size loss is gone compared to the
previous version, we're 68 bytes bigger than before buffer-less
parsing. Reason is the new function disk_parsep() in
pff_diskio.h. RAM usage is still low.
