[Blob] Using blobs dynamically set

[GwenGuts]

Hi,

First, I'd like to thank you for the great work with you library, it works smoothly !

But, I have a problem, it seems you can't set the src in the simple-ar attribute of the a-entity dynamically, it has to be set static on the html page.

Do I have to manipulate the DOM to create dynamically all of the required tags, like that:

const aEntity = document.createElement('a-entity');

aEntity.setAttribute('simple-ar', 'src: ...');

?

Thanks for your response !
