deltaParse :: Parser ByteString DeltaSource
parse a delta. format is 2 variable sizes, followed by delta cmds. for each cmd: * if first byte MSB is set, we copy from source. * otherwise, we copy from delta. * extensions are not handled.
deltaRead :: ByteString -> Maybe DeltaSource
read one delta from a lazy bytestring.
deltaApply :: ByteString -> Delta -> ByteStringSource
apply a delta on a lazy bytestring, returning a new bytestring.
