Look at replacing robust-orientation with robust-predicates

[rowanwins]

We've had a few issues upstream in Turf because of robust-predicates causing an issue.

Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'unsafe-inline'

See related issue in robust-orientation

Potentially robust-predicates could be used to replace it, however in swapping one for the other there were changes

So It's not quite a drop in replacement yet but I thought I'd flag it here and I'll also open an issue in robust-predicates

Likely an issue with how you use robust-predicates (see my comment there).

Replacing the dependency is a great idea, I completely forgot concaveman used robust-orientation! One thing to note here is that monotone-convex-hull-2d also depends on robust-orientation, so we would need to replace the convex hull dependency as well.

The convex hull code seems small enough to just inline here: https://en.wikibooks.org/wiki/Algorithm_Implementation/Geometry/Convex_hull/Monotone_chain#JavaScript
