Add account new command

[igamigo]

Draft of account creation command and tables to store account data

• Updates migration file to add tables relevant to accounts
• Adds a command that creates a new account and stores it in the tables
• Adds a "testing" feature that uses the testing feature from the base crates so that the PoW seed grinding is not as expensive
• Minor refactors to the command line args
• Implements 3 "templates" (basic mutable, basic immutable, and fungible-faucet) for easy account creation

Test with cargo run --release --features testing -- account new fungible-faucet -t TEST -d 10 -m 10000 and then cargo run --release --features testing -- account list

TODO:

• Add some tests mainly related to the new tables (added a simple test, adding more in future PRs)
• Add a way to define the fungible-faucet parameters (ticker, decimals, initial supply)
• Add a way to generate the remaining types of accounts (only NF-faucet missing)
• Add a way to generically create wallets (with a local code file, etc.) (left for future work)

Currently ModuleAst does not derive Serialize so we might have to add that in the corresponding repo if we want to store that as a serialized blob

Looks good, thanks! I've left some comments - primarily around coding style.

I've opened the following issue #19 to discuss if we should consider using an ORM to manage our database models, migrations and queries.

Looks good - thanks for clarification on the account id i64 representation. Added a few more comments.

Looks good, thanks! Once we have changes the branch for miden-lib and miden-objects back to main we can merge. I've also added a comment regarding adding the relations to the accounts table - should we do that now or part of a follow up PR?

[frisitano]

we typically avoid spacing between imports.

[frisitano]

should we define the relations to the account_vault, account_code and account_storage tables here?

Creating a follow-up PR for this
