feat: added support for ESM (ECMAScript modules)

BREAKING CHANGE: due to added ESM module support Node.js version with
ESM implementation bugs are no longer supported, this only affects early
v13.x versions. The resulting Node.js semver range is
`^10.19.0 || >=12.0.0 < 13 || >=13.7.0` (also taking into account the
`got` dependency update)
