Remove extra-lint

- standard enforces 'let' and 'const' now
- I've never been a fan of the <100 chars per line rule since it violates the standard philosophy. it should be possible to write conformant code without needing a tool, so 'magic numbers' like 'no more than X lines/chars/statements' are not ideal
