add local arrow data files support via vega-loader-arrow? 🤔

[RandomFractals]

literally, the only supported data formats type missing in this ext. for prototying vega charts offline and in code.

I'll add it if devs using Vega Viewer vote on it. I doubt there are many or any using both tech stacks, even tho I like arrow data format a lot!

see this repo for more info: https://github.com/vega/vega-loader-arrow

[RandomFractals]

I might add it in the next ext. release using this bit :)
