perf(file): Compress bit more aggressively

[surajshetty3416]

Current "Optimize" is quite ineffective and hardly reduces the size of the image. Websites continue to load big images causing slow page loads.

Proposal is to reduce the default "max_resolution" and to atleast reduce the resolution to 80% to maximise the saving.

This should be fine since users explicitly click on optimise and their primary reason for it is to reduce file size. Assuming that they are fine with minor quality degrade.

I tried compressing a image file of size 1.41M
Optimised file size: 1.36M (before this fix)
Optimised file size: 461.3K (with this fix)

Other:

• Now system will display formatted file size on setting "File Size" in "Options" of Int field.
