upgrade strxml to fix warnings related to tap included in build

[kriscarle]

This was still using the original version of strxml that included tap in dependences. All the tests are passing again.

This is mainly to fix security warnings coming from old versions of uglify etc. that are pulled in by this repo https://snyk.io/test/npm/tokml/0.4.0

Will there be any work done on this?

Now that nsp check no longer works and npm audit does not allow ignoring vulnerabilities as of now (not even mentioning yarn audit...) this is pretty problematic.

@kszafran @bobi7 It doesn't seem like Mapbox is still using or maintaining this code, so I went ahead and converted this PR to a fork, and published v0.5.0 here https://www.npmjs.com/package/@maphubs/tokml

@kriscarle I actually switched to your fork yesterday. Thanks for publishing it to npm!
