Might want to split this into something like "max V length" since the sign and seq are separate and we need to enforce that v is no longer than 1000b

I added a const MAX_V_LEN and some documentation to keep it more clear. We need to do the check on MIN_MESSAGE_LEN at the beginner of decode() regardless so we don't try to access an index out of bounds.

Ah that's a mistake because copied it blindly from web5-dart. Here's a PR to update it in dart TBD54566975/web5-dart#87

This PR does not yet make use of the bep44 mod. In a follow up PR that implements
DidDht::create, this encoder will actually be used.See also the dart implementation: https://github.com/TBD54566975/web5-dart/blob/main/packages/web5/lib/src/dids/did_dht/bep44.dart
