Support use of abbreviated 4-letter BIP39 words about libwally-core HOT 5 OPEN

@gwillen what are the pros/cons handling this at the GUI/app layer rather than at the wally layer?

Our mobile apps already suggest the right word at 4 characters or less depending on the word and i think you still need to keep the full dictionary to show it to the user to generate mnemonic etc

I am not against adding it though

We are using the wally layer to create python commandline tools. So we don't have any way to take advantage of autocomplete and such happening at higher layers. If there's another good approach for commandline tools I'm all ears!

(If the answer is that we should implement this in the tool, I don't disagree although it would be nice to get the benefit of all Wally's existing support for wordlists and such. Realistically this tool will probably never be used with anything other than the fixed BIP39 English wordlist, but I though more general support seemed likely to be useful.)

makes sense - if it's done in wally then it can be reused in all lib/apps/cli/gui so happy to review PRs or anyhow add it to the features wishlist

Just add a PR regarding this issue for your perusal.
