Yarn workspaces, keep select packages for now

[mikedotexe]

Got the select packages compiling to CommonJS and ESM.

There are probably some more issues to address, but this branch is an effort for a fresh start. It's pointing to a local near-api-js. I'll keep this as a draft in case others wish to compile these (and potentially work through what surfaces)

I have my local near-api-js pointed to this branch:
near/near-api-js#1394

Try it

nvm use --lts
npm i -g yarn
yarn set version berry
yarn -v

You should see a version greater than 1, currently it's at 4.5.0.

yarn
yarn workspaces foreach --all -t run compile:cjs
yarn workspaces foreach --all -t run compile:esm
