[WIP] Adding the WebWorker feature to WebARStudio

[kalwalt]

This PR will add the WebWorker feature to the editor.
Features and code changed:

• new jsartoolkitNFT with WASM as single file.
• remove old jsartoolkit5 libs
• remove all arController references outside the Worker (i.e. in the main thread)
• new listeners to pass data from Worker to markerRoot
• new getUserMedia function to pass the video
• check if video is closed/deleted correctly
• check if model/mesh is displayed
• fix issue [Bug] unable to display a model #4

JsartoolkitNFT from master branch https://github.com/webarkit/jsartoolkitNFT

At the moment it can track the NFT marker, because i can see the messages in the console. The video is displayed but is not correclty closed/deleted when it is pushed the stop button. This need to be fixed. And model is not displayed probably need to be fixed some retrieved values (matrix or related stuff)

[kalwalt]

Things to do:

• solve the video issue( not correctly stopped)
• improve the mediaStream part
• remove old dead code that refer to arController
• better webWorker
• solve issue with matrix (camera matrix?) cube appear as out of the screen.

I am back on this. 😄
trying to solve and finish this PR. I'm getting this error while detecting the pinball marker:

arcontroller.component.js?version=0.64:109 Uncaught TypeError: Cannot read property 'setPosition' of undefined
    at arcontroller.component.js?version=0.64:109
    at found (webWorker.js:189)
    at Worker.worker.onmessage (webWorker.js:60)

Probably markerRoot is not correct? I should compare my version code with the previous one, I think something is wrong in my implementation...

[kalwalt]

@ThorstenBux i will apply that fix also in the master branch. Anyway this should be tested, before to merge it. I think we are very close for a new release...

If someone want to try, test WebARStudio at this link

Tested again the code: with the latest, sometimes i receive the error already reported, not the same but it came from that:

arcontroller.component.js?version=0.64:91 Uncaught TypeError: Cannot read property 'childNodes' of null
    at arcontroller.component.js?version=0.64:91
    at found (webWorker.js:189)
    at Worker.worker.onmessage (webWorker.js:60)

it appear when i stop the video and restart the simulation.
The model also appear too big even if i set up to small size. I have no idea how to solve and why now this happens.
