Eliminate Buffer dependency

[jonathantneal]

This pull requests continues where #925 leaves off.

Changes from that PR:

• Checkout existing PR and rebase with current main branch.
• Remove unused arraybuffer-equal dependency from prior PR.
• Minor tweaks to following formatting conventions in current project.
• Run npm run add-contributor and follow the prompts to add yourself to the README

Notes:

• I am open to corrections and changes. I have only somewhat familiarized myself with the project.
• I was unable to run the tests successfully from the main branch, making it difficult to debug this feature branch.
• I had difficulty using nps, namely isolating individual scripts for debugging. I found commands to run via npx.
• In order to build the project locally, I needed to use NODE_OPTIONS=--openssl-legacy-provider.

  # example
  NODE_OPTIONS=--openssl-legacy-provider npx webpack --config webpack.config.cjs

You will need to fix the broken unit tests.

There is an error: "Failed to tree-shake index.js":

I'm not sure why

Please update with main since there was fixes to unit tests. Also you will need to resolve conflicts. I'm not sure if you will be able to do rebase if there are conflicts.

You can try to remove yourself from README.md and .all-contributorsrc rebase and add yourself again. You can run interactive rebase and remove the commit where you added yourself.
