NFD R1 disk image support

[joncampbell123]

So far, NFD R0 is the only version supported.

I found a PC-98 game stored in an NFD R1 image (Tsumeawase collection, [PC98][さ][ザインソフト] クルージュ [NFD].zip).

Hopefully the converter script source code I cloned from another project can provide enough information to describe how to read it.

I posted a copy on Hackipedia, converting SJIS to UTF-8 for more universal readability using GNU iconv:
