New masking - object mask data in the external file

Hello, I'm the author of a Premiere Pro plugin called "Mask To Transform" which is able to convert the tracked mask into position/scale/rotation keyframes that can be applied to a Trasnfrom effect to e.g. make motion graphics "stick" to an object in the scene etc. My plugin is officially available in Exchange: here's the link https://exchange.adobe.com/apps/cc/105713/mask-to-transform

Now with the new masking soluion in Beta my customers are writing to me that my plugin stopped working and it would be amazing if I can make it work with the new (and admittedly pretty awesome) object masking. The problem is that the object mask data sits in a binary file on disk and there doesn't seem to be an easy way to read it. 

So my question is: for the purposes of extention development is there a way to somehow read the data stored in these object mask files?

Thanks,

Kamil
