asn.1 codec could derive from list for SEQUENCE, SET, etc...

[samrushing]

The current asn.1 codec maps some constructs directly to their corresponding objects, (INTEGER, SEQUENCE, etc...) and maps everything else to a tuple of (kind, tag, data).

It might be nice to use derived classes to indicate exact asn.1 types. This would also help to make the codec a round-trip one: you can feed the output of the decoder to the encoder and get back the original asn.1.

For example, have a BITSTRING class derived from bytes, have an ENUM class derived from int, etc...

With these changes we could still have efficient and easy-to-use output.
