WIP - adding NFT artoolkit feature to the component

[kalwalt]

With this PR we try to add the NFT feature into the artrackable.component.js and arcontroller.component.js

• [x] creating an option on the inspector with a Pinball marker
• [x] load the NFT marker
• [x] setting a getNFTmarker event listener to retrieve incoming data

Note that for the moment we will test the not worker approach. Worker support will be added later.
