No.  I hope to have enough time to code this up myself this time.
It's a Small Matter of Programming to grovel over the filesystem to
figure out what a particular sector does.

I'm a little disappointed that fsdb doesn't do this.  Maybe I should
start by hacking on fsdb.

I have recently discovered the "conv=noerror,sync" option to dd.  In
combination with a background shell script which repeatedly runs
"atacontrol mode 0 udma6 udma6", this lets me recover all the readable
bits from a broken filesystem quite fast.
