Increase assets limit for application from 150

I understand for many games 150 images is not a limit, but for some it is very limiting.

Can you plese:

• Increase the limit to 600 or more.
• Allow sending images of lover quality encoded as BASE64
• Allow loading images from game if installed, with fallback
• Allow texture mapping, so we can have multiple images in one asset

We would like to show players character and location, in the rich presence, but 150 images is not enough.
