CLI Update

The new release of squid CLI introduces a cross-platform tool to run user-specified commands and scripts with a single sqd command.

This is a replacement for Make and package.json and has the following advantages:

• The script descriptions are displayed in sqd --help
• Consistent execution across different shells and platforms

Thanks to these features, various dev tools of Squid SDK for EVM and Substrate networks now come pre-defined in the commands.json file. The tools are now invoked with sqd in a unified fashion (no more magic Make spells!), e.g.

sqd migration:generate

Commands support dependencies for convenient command chaining, e.g.:

"migration:generate": {
    "description": "Generate a DB migration matching the TypeORM entities",
    "deps": ["build", "migration:clean"],
    "cmd": ["squid-typeorm-migration", "generate"],
},

This dovetails nicely with the new abi template supported by sqd init The ABI template scaffolds a batteries-included squid indexer from a contract ABI. Moreover, public contract ABIs can be fetched directly from Etherscan so in many cases it suffices just to throw in the contract address, run sqd generate (defined as a commands.json script!) and enjoy the fast indexing with zero coding.
