Roughness

[iHiD]

Hello! Love this library - we use it on the home page of Exercism and I'm currently adding it to Kaido too 🙂

I'd like to make the lines slightly less rough, and was wondering if you'd be interested in a PR that allows consumers to vary the roughness option via the options hash? ie make this configurable: https://github.com/rough-stuff/rough-notation/blob/668ba82ac89c903d6f59c9351b9b85855da9882c/src/render.ts#L11

Thanks! :)
