vs-code: Add json files for the tags.

[KevinJump]

For a vs-code version see branch : https://github.com/KevinJump/UmbSense/tree/vs-code

the vs-code extension uses json files to define the tags, attributes and values. https://github.com/KevinJump/UmbSense/tree/vs-code/tags

it seems to make sense to have a json file for each tag, as that will give us some segmentation of the tags. it will generate a lot of files but we should be able to do something to merge them when built
