feat: support @mapbox/node-pre-gyp workflows

[guybedford]

Resolves #199.

[styfle]

Should we replace the legacy node-pre-gyp with the new mapbox one here or keep them both?

[guybedford]

We can keep both for legacy compat, possibly dropping the old one in a subsequent major.

Thanks again 👍

@styfle how about dropping support for node-pre-gyp now? It's been some time and it should get rid of the npm install warning plus reduce the package size :)

EDIT: we could also get rid of mkdirp assuming Node.js >=10.12.0

[styfle]

I think we need to keep node-pre-gyp since it still gets 2.7 million downloads a week and has 812 packages that depend on it. See the comment above.

Regarding mkdirp we can drop it in #260, thanks!
