Add support for FRUs with no needing packed 6bit ascii
Add support for FRUs with no needing packed 6bit ascii

Fixed a bug with max_size that caused some fru creations
to fail due to max_size not initialized.

Nothing in DMTF is explicit about requiring packed 6bit.
It certianly is a space saver but for those that want their
FRU data in ascii they now have that option
