Feature request: Support Catalyst apps

[raxityo]

Related to #7 but a feature request

Example structure of the Mix app, which is a catalyst app:

$ ls -l /Applications/Mix.app/
total 0
lrw-r--r--  1 root  wheel   15 Jan 20 09:20 WrappedBundle -> Wrapper/Mix.app
drwxr-xr-x  5 root  wheel  160 Jan 20 09:20 Wrapper

$ ls -l /Applications/Mix.app/Wrapper/
total 16
-rw-r--r--   1 root  wheel   618 Jan 20 09:20 BundleMetadata.plist
drwxr-xr-x@ 87 root  wheel  2784 Jan 20 09:20 Mix.app
-rw-r--r--   1 root  wheel  1353 Jan 20 09:20 iTunesMetadata.plist

$ ls -l /Applications/Mix.app/Wrapper/Mix.app/
total 41656
-rw-r--r--@ 1 root  wheel      6613 Jan 18 12:59 ActivityCell.nib
-rw-r--r--@ 1 root  wheel      3063 Jan 18 12:59 AppIcon60x60@2x.png # AppIcon 
-rw-r--r--@ 1 root  wheel      3787 Jan 18 12:59 AppIcon76x76@2x~ipad.png # AppIcon used in the dock
-rw-r--r--@ 1 root  wheel    975960 Jan 18 12:59 Assets.car
# ...
# Rest of the files

I am happy to open a PR for this!
