Multiple improvements added

[redd1ng]

I have added the following improvements:

• Handle EncryptedPolicyBody for platform and remediation scripts (fixes Encrypted Intune policies #11)
• Files are now written to disk instead of stdout. This helps when a tenant has a large number of scripts and fixes the case where encoding errors threw an exception.
• Added a try except to apps download so it will continue to download the other apps in case an error occurs.

It will create the following folders when downloading scripts/apps, saves the files according to its type in the dedicated folder and makes it easier to search for specific keywords trough all files.
