how close is this to being able to produce a binary identical FFS image
to the existing tooling?

We have a different CSV format for FFS in phosphor-mboxd too, perhaps
Adriana can chime in if it's possible/plausible to move to just one
representation, as this could help simplify our PNOR building process.

I'd *really* like to rip out openpower-ffs and other related crap from
the op-build process and just replace it with this, largely because this
has a remote chance of being maintained and a remote chance of not
bringing in 13,000 lines of useless junk with it.

In theory at least, ffspart ond the openbmc image building utility could
just take the same input and output a different image.
