  # generic MSE fuzzer, we use distinct fuzzers corresponding 1:1 to a set of
  # mimetype+codec strings for now because:
  # a) the SourceBuffer implementation must be constructed to expect a
  #    particular bytestream type and (set of) codec(s); it does not
  #    auto-detect those from the appended media, and
  # b) maintaining the association of a (mutated) corpus item with the same MSE
  #    SourceBuffer configuration requires associating that item with the same
  #    mimetype+codec string. The benefits are simpler fuzzers and the ability
  #    to slice per-fuzzer coverage stats. The costs include more fuzzers, risk
  #    of new bytestream types or codec fuzzing gaps, and more potential
  #    duplicate bugs from different fuzzers for common issues exposed across
  #    mimetype+codec string variants.
