trait BitsCharset extends Serializable

Charset enhanced with features allowing it to work with Daffodil's Bit-wise DataInputStream and DataOutputStream.

Daffodil uses BitsCharset as its primary abstraction for dealing with character sets, which enables it to support character sets where the code units are smaller than 1 byte.

Note that BitsCharset is NOT derived from java.nio.charset.Charset, nor are BitsCharsetDecoder or BitsCharsetEncoder derived from java.nio.charset.CharsetDecoder or CharsetEncoder respectively. This is partly because these Java classes have many final methods that make it impossible for us to implement what we need by extending them. But more importantly, we need much more low level control about how characters are decoded what what kind of information is returned during decode operations. Getting that information with the limitations of the java Charset API become an encumbrance. Replacing with our own Charset decoders grealy simplifies the code and allows for future enhancements as needed.
