String decode(List<int> bytes, { bool allowInvalid })

Decodes the ASCII bytes (a list of unsigned 7-bit integers) to the corresponding string.

If bytes contains values that are not in the range 0 .. 127, the decoder will eventually throw a FormatException.

If allowInvalid is not provided, it defaults to the value used to create this AsciiCodec.
