Support Positive globs

[bzhu94]

Is your feature request related to a problem? Please describe.
Currently for my scenario, I would like to run DevSkim analyze for specific file types (only Powershell in this case) across my repo. Currently the Globs parameter doesn't seem to support inversion globs such as **/*,!**/*.ps1 for my scenario to work.

Describe the solution you'd like
Either support inversion globs via the Globs parameter, or better yet, create a new positive glob parameter in the analyze command to list files / directories to include in the DevSkim command.

Describe alternatives you've considered
As a workaround, I need to list out all the current supported file types by DevSkim in the Globs parameter except for Powershell for my scenario
