util/nvmutil: add cat16 and cat128 commands

these take any file size of gbe file: 8KB, 16KB
or 128KB. so does the normal cat.

then you can use cat, cat16 or cat128. these
output to stdout, the corresponding size in KB.

0xFF padding used on the larger files. on the
larger files, the first 4KB of each half is the
GbE parts, and everything else is 0xFF padding.

now you can resize gbe files easily, example:

./nvmutil gbe128.bin > gbe8.bin

yes
