docs: Test if this StreamConfiguration and a paired EncodingConfiguration define
  a Subset compliant stream. FLAC defines a subset of options to
  ensure resulting FLAC streams are streamable.
  @param ec EncodingConfiguration object to check against
  @return true if these configurations are Subset compliant, false otherwise.
