standalone software to create a gocryptfs folder without the need of FUSE #918

Hi, based on the work of gocryptfs-inspect and its eme-supporting fork I built a standalone python script that takes a plain folder and creates a gocryptfs folder that can then be mounted!

Context: My use case is that people have to upload data without trusting our servers, and we can't assume that they have FUSE available.

The created folder has the feature flags (ref)

"FeatureFlags": [
 "HKDF",
 "GCMIV128",
 "DirIV",
 "EMENames",
 "LongNames",
 "Raw64"
]
