feat: add ESM support, remove make-error dependency

BREAKING CHANGE: Extending from `Error` has been simplified by getting rid of the
`make-error` dependency; this _may_ be a breaking change. Additionally, `exports`
field has been added to `package.json`.

BREAKING CHANGE: Minimum supported Node version bumped to 18
