feat: add support for Foundry keystore accounts

[z80dev]

What I did

Added support for Foundry keystore accounts fixes: #

How I did it

Implemented AccountsContainer and a child class of KeystoreAccount handling the differences between ape's keystores and foundry's.

The main difference is that Foundry keystores don't include the address so we have to compute that, which requires unlocking and getting the private key. We do some caching and sometimes return None to make things more convenient.

How to verify it

After installing foundry, run:

cast wallet new testwallet

then after installing this plugin run:

ape accounts list --all

output should include:

Found 1 account in the 'foundry' plugin:
  *address encrypted* (alias: 'testwallet')

Needs some tests maybe

yeah I think this week I'll have time to add some.

@fubuloubu do you have any ideas about what to return when an account is locked, since right now we have to return AddressType the typechecker will fail if we keep returning a string?
