Targeting a source density modifies the files in that folder

[robisaks]

using --density-xxhdpi updates modified date of assets in the drawable-xxhdpi. This is not a big issue, however it does trigger a re-upload of those assets to file services (like Google Drive and Dropbox) and also nullifies the ability to sort by modified date. Pretty minor issue, but thought I would report it just in case.

Thanks for the report, this is because those assets are simply resaved without resizing. We should probably just skip those assets instead.
