Subject: [PATCH] Added a couple new Errors that can be supplied during
 transmutation.

Added an error for a corruption detection of the given bytes. This was
added so that an inproper CRC code when reading a PNG file could
throw an Error.

Added an error for an invalid value being transmuted from the given bytes.
This was added so that an Error can be thrown when a value outside of
a given range is parsed.
