Revisit CLI tool for relevant project actions

[Hyodar]

We have a projectt CLI tool we don't really use on cli. As mentioned in #220, we should add utilities to it to simplify some workflow actions, especially since it's more manageable than a Makefile for most situations and it's also easier to add documentation.
Some examples:

• Generating bindings and updating anvil states (Improve anvil state and binding generation workflow #220)
• Utility for funding NEAR testnet accounts (Add utility for funding NEAR testnet accounts #222)
• Starting chains with initial anvil state (start-(.*) on tests/anvil)

I personally don't really care much about those e.g. spawning shell commands or such and depends on something being previously installed, the important part is we standardize a way to do these processes and have it in a more organized manner.
