Add ability to dump APK packages

[TheZ3ro]

This PR:

• fixes the pullFolders function of the ADB client to actually pull folders. Symlink-resolution is not supported by the ADB sync protocol so I don't really know how are we supposed to handle them, for now the client just ignores them. this fixed both the Log and the Temp modules
• unify the 10 seconds timer in a single constant so can be easily put to 1 during development avoiding waiting time. maybe we should put this behind a BUILD config.
• implemented the APK dump for the Packages module. downloading all the APK in a phone takes quite some time and space so for now I've put a simple logic in libmvt APKStaticAnalyzer.kt to rule out suspicious APK to dump.
• added some TODOs here and there
