Look into dependency sizes for CLI and project

[stwiname]

The polkadot start installs about 800MB of dependencies right now. This includes the CLI as a dependency. We should look at reducing this.

This file is the output of du -h -d 1 | sort -n on node_modules with the sorting fixed with the units modules_size.txt

Starting with the larger dependencies I think there are a few easy wins, these changes will probably need to be made to common and types packages for each chain.

• [ ] Ensure dependencies are actual required dependencies, if not they should be moved to devDependencies (e.g prettier)
• [x] Update oclif and use correct sub packages. Currently we have aws-cli as a transient dependency which is 90MB
• [x] Move ethereum codegen to @subql/common-ethereum. This will ensure versions of ethers remain the same between different packages
• [ ] More specific imports. Do we need @polkadot/api as a dependency if we only use @polkadot/types
• [ ] Investigate a way to make the CLI more modular, currently it supports every chain which brings along the associated sdks for those chains. typechain could be a good example where you need to also install the target
• [ ] Look at bundling the CLI into a single js file (e.g webpack)

The linked PR doesn't relate to this?

This was incorrectly marked as fixed, reopened

After the oclif update we're down to 580MB

Closing this as we've reduced the size from >300MB to <100MB. If this is picked up again looking into the dependencies of class-transformer would be the next place to look.
