tslint 6 compatibility

[snebjorn]

Describe the bug

I was wondering if the tslint version could be bumped to 6, it's currently 5

I keep getting peer dependency warnings :(

[KBeDevel]

I think this could be ignored due to ESLint migration :/

[snebjorn]

The ESLint migration is possibly months/years away.

I'd be willing to make a PR
