This will replace the previous implementation which does basic decoding. This
is to be a more thorough dissector. It will also include support for decoding
vendor-specific fields.

I did but the problem was that this data was contained in a binary tree which
is created using seasonal storage. I will have to re-work this. The plan is to
register an additional array of header_field_info structs. This array would be
generated at runtime using values read from a vendor-supplied file. This would
be generated at starup and persist until Wireshark is closed. Are there any
other dissectors/examples that do something like this?
