Fix #111

[matburnham]

Fixes #111 to build with Node 12 and Node 14.

[matburnham]

Notwithstanding #114 this seems to pass all tests and works with the code I was originally trying to use with Node 12. Travis-CI passes except for Node 4 which was already broken.

@springmeyer @joto Can we please get this merged?

Also, will you accept a pull request that removes unsupported NodeJS versions? (i.e. v4, v6, and v8)

[springmeyer]

@awendt I'm no longer in a position where I have time to do releases or test them. This one in particular might get the code to compile but it would require testing to ensure it runs correctly. Also, the right solution here is to port to NAPI, but that is a big effort. So, I must ask, would you or @matburnham be able to accomplish what you are trying to do with osmium-tool instead of node-osmium?

[awendt]

@springmeyer Thanks for the heads-up!

I have been using node-osmium for a script that checks the Haversine distance for each way and drops the ones that are shorter than a threshold. From the docs, I don't see how this can be easily replaced with osmium-tool but I'm sure I can find a way.

Thanks for the PR. I am sorry it took so long to get it merged. Unfortunately node-osmium is at the bottom of my priority list and it always takes me some time to come around to it.
