Updates dependencies and removes unneeded Lodash libs (#64)

- eslint node plugin is no longer maintained, so switching to the eslint recommended presets that are based on our es2021 settings
- removes lodash dependencies that can be replaced by basic native code.
- version bump in prep for a release of the changes
