Smallest buffer ratio

Looks like it does not accept Number.MIN_VALUE as ratio...

My tests gives me 10^-9 as smallest value

Since this is (currently) using JSTS, it's subject to jsts.geom.PrecisionModel's settings. I think we could override with a more detailed precisionmodel, but the plan is to be removing the JSTS dependency sometime in the near future

Ok! 10^-9 is fine meanwhile (https://github.com/Turfjs/turf-cut)
