JavaScript Dynamic Imports

[jamiebuilds]

OctoLinker version: 4.9.0

JavaScript is adding dynamic imports which look like this:

import("./module") // >> Promise<Module>

OctoLinker doesn't appear to support these yet, it would be nice if it did.

This seems like it should be relatively straight-forward to implement, if anyone would like to. You'll need to change require(\.resolve)? to ( require(\.resolve)? | import ) here, then port some valid and invalid tests into the corresponding forms using the dynamic import syntax.

Hi, I am not sure how the CI works, but I forked and created a branch called Issue-#315.
