Rebuild of Nodejs Bindings

[matthewkeil]

Follow-up to PR #147 and related to Issue #153, Issue #149 and Issue #118.

Inclusions

• Polish nodejs bindings #153 - Polishes the node bindings
• Unit tests for arg and return types
• tools folder with utils, dev, publish scripts
• Cleanup node bindings #149 - Updated files/filestructure in bindings/node.js
• npm package error #118 - Add -fPIC to linux build flag

Notes:

• I am adding some additional unit tests for the bindings today but those should not affect the code as I was running the code on watch while I worked and saw the errors being thrown

I just saw the workflow fail and am updating that now. Will push a commit in two shakes. Just want to test it first

I added the -fPIC and the library builds fine using npm on ubuntu. But now there is an error when the tests run symbol lookup error: c-kzg-4844/bindings/node.js/build/Release/kzg_bindings.node: undefined symbol: blst_p1_uncompress. I will continue to debug in the morning

The CI using ubuntu was working with the make commands and only broke after the code changes and switching to npm command. I can try to move back to the make command for this PR and can perhaps do the npm fix on a subsequent PR to not hold things up.

In the mean time I added a matrix strategy to the workflow to test the bindings against mac/windows/linux for node versions 12, 14, 16, 17, 18 so we can see build/test results against a few different environments until things are stable

To ease reviews I would close this PR and split into progressive chunks:

non-core logic

• Update CI workflow(s)
• Add eslint
• Update misc config files
• Expand tests against current logic in main

core logic

• Polish bindings with min set of changes for the items Polish nodejs bindings #153
• Then, propose re-write

Closing this and will reopen as several separate PR's
