A tool for generating a TS file from a lone Anchor IDL JSON file.
Creates a type and an object for the IDL. Lower camel cases the account names.
Usually this TS file is generated when building an Anchor repo. https://github.com/coral-xyz/anchor/blob/master/cli/src/rust_template.rs#L222
Sometimes you just have another project's JSON file and want a TS file for your client.
