Read details from Contents.json

[avioli]

Is it possible to read the sizes and filenames from Contents.json and use that?

@avioli should easy to do, how would you use the command? Would something like

icongen generate --contents-json=/path/to/Contents.json

work? With potentially an --in-place option to allow recreating the app icons in place from the Contents.json location.
