Punchplate Support

Punchplates use two different encoding mechanisms:

- [ ] alphabetic, just the first four letters of the seed word
- [ ] numeric, every seed word is numbered, and a lookup table is used

Both of these should reproduce a full mnemonic seed phrase.

Multiple seed formats should be returned: `full`, `alpha`, `num`
