Integrate farmOS.js 2.x into Field Kit

[jgaehring]

Most of the work in #430 and #431 will happen in the farmOS.js repo itself, but once that's done, there will still be work to integrate it into Field Kit itself. Hopefully these are not huge changes and should go smoothly, but I should be prepared for there to be a few unforeseen bumps in the road.

At the end of this, and once #443 is done, I'll merge the changes on my v2-alpha branch into develop. After that, develop will have forked pretty far from the v1 and v1-migration-notice branches, so just prior to that, it might be a good time to rebase on the pending dependabot PR's:

• Bump dns-packet from 1.3.1 to 1.3.4 #450
• Bump trim-newlines from 3.0.0 to 3.0.1 #451
• Bump path-parse from 1.0.6 to 1.0.7 #453

With the completion of #455, I think this is sufficiently complete, at least for the alpha release. After this I'm going to shift my focus to the farmOS.js beta milestone, which will have its own updates to re-integrate here, but that should be addressed by FK's own beta milestone.
