Statamic v6 support

[kevinmeijer97]

Are you planning on adding support for Statamic 6?
We're using the builder for https://github.com/rapidez/statamic and we're looking to add v6 support soon.

Yes! This is a side project for me, as I have switched jobs and no longer work primarily with Statamic. Your assistance would be greatly appreciated.

I’ve already tested Statamic Builder with Statamic v6, and so far it works without any changes needed. Everything seems to function as expected.

That said, I’m not using the full feature set yet and probably haven’t tested the newer functionality introduced in Statamic v6.

We also haven't noticed any breaking changes when upgrading to v6, i've opened a PR for this (#81).
Some further testing might be needed to make sure everything is covered.
