Allow to configure seed via a BIP 39 mnemonic

[tnull]

Fixes #47, Based on #64

Since it's unblocked now, we allow users to give the seed via a BIP 39 mnemonic.

Does this also expose the ability to create a mnemonic?
I.e via BDK's Mnemonic() function.

As I currently use BDK to generate the mnemonic for new users I would like to be able to do the same with ldk-node

In Rust we to this end re-export the bip39 crate for users to have it handy. In bindings, I imagine we'll expose this as a function that just takes the Mnemonic as a string and builds the object for the user.

I would also want a function that GETs a new mnemonic, for first time users.

Rebased on main.
