Merge #11951: Remove dead feeest-file read code for old versions

62e7c04 Remove dead feeest-file read code for old versions (Matt Corallo)

Pull request description:

  0.15.0 introduced a new feeest file format, and support for parsing
  old versions was never fully added. We now simply fail to read the
  old format, so remove the dead partial-implementation.

  Follow up to #11273.
