CLI / ATA Delegation

[murmky]

Adds two commands to the CLI:

• delegate_token_account, which delegates a token account owned by a vault to a designated third-party key
• delegated_token_transfer, which enables the new key to withdraw the funds from the specified token account where the delegation was made

Requires #196 to be merged first (branch is rebased on ck/more-cli).

Hey @murmky! Thanks for the PR!

Could you kindly merge in master and then run ./format in the root directory and fix any errors? This will allow our CI/CD to pass!

Cheers!

@coachchucksol should be better now
