Log version-specific features that raise requirements

See original GitHub issue

Currently running vermin on a project folder will display the minimum required Python version. However, it doesn’t go into any detail for why a project requires that version.

C:\>vermin U:\Documents\Scripts\wfc_helper
Detecting python files..
Analyzing 13 files using 4 processes..
Minimum required versions: 3.6
Incompatible versions:     2

To help users learn why a version is required, I propose listing what features a project uses to require a specific version of Python.

C:\>vermin U:\Documents\Scripts\wfc_helper
Detecting python files..
Analyzing 13 files using 4 processes..
Minimum required versions: 3.6
Incompatible versions:     2
Features:                  f-strings (3.6)
                           import typing (3.5)

Alternatively, if a folder is specified, Vermin could specify which file or line number caused the current requirements.

@netromdk Confirmed. -vv is working as intended in v0.4.3. This feature does exactly what I was looking for. Thanks for the fix!
