Integration with the SDK (MVP cont.)

[digorithm]

EDIT(iqdecay): I have taken over this PR, and would like to get this merged "as is", with the refactoring being done in #11 and some more work being done aside.

Continuing the features documented here #2.

This PR integrates the forc wallet plugin with the SDK, adds wallet encryption and storage, wallet listing.

USAGE:
    forc-wallet [OPTIONS] <SUBCOMMAND>

OPTIONS:
    -h, --help            Print help information
    -o, --format <FMT>    [default: json] [possible values: json, toml]
    -V, --version         Print version information

SUBCOMMANDS:
    help      Print this message or the help of the given subcommand(s)
    import    Import a wallet from mnemonic phrase
    list      Lists all wallets stored in ~/.fuel/wallets/
    new       Randomly generate a new wallet. By default, wallets are stored in ~/.fuel/wallets/

Wallet creation now requires a password for the encryption process. Password input is protected and the outputted wallet is outputted in a safe way that can't be stored in the terminal's history.

Wallets are stored in ~/.fuel/wallets. To open these wallets you need the password you used to create them.

Creating the wallet:

./target/debug/forc-wallet new
Please enter a password to encrypt this private key:
Please confirm your password:

Then the safe output:

JSON Wallet uuid: 3ef27797-fd47-45da-b9a1-6d4f7b1f5164

Wallet public address: 3069ea2d1cca428fbe91137943dfaa5f193695730ef62d1f940fee7ffa465326

Wallet mnemonic phrase: space agree swing obvious hover chimney liquid tonight never pony electric useless

LGTM

lgtm

[iqdecay]

Appreciate the suggestions a lot, but this PR is more about putting "the basis" in, #11 is about refactoring.

Couple questions

1. The Command enum takes 3 fields while the help message lists 4. Should the enum also contain a help field? When the main function is run it doesn't seem to match for help so I assume some magic happens somewhere and if help is seen then the program does not continue
2. Can someone explain to me the purpose of the uuid here?

[iqdecay]

• The help command is directly integrated inside the clap module.
• The UUID is, afaik, here to ensure that we generate wallets that have unique ids/names and avoid collisions.

still lgtm, give another approve please just want to move forward lol
