Global tool throws unhandled exception for empty file

[jhoak]

Describe the bug
When running DevSkim on an empty text or powershell file, the tool exits and spits out the stack trace.

To Reproduce
Steps to reproduce the behavior:

1. Create a new empty file
2. Run devskim analyze
3. See the error.

Expected behavior
Exit the tool with no messages.

Thanks for your report. I'll investigate a fix this week. Likely just requires updating dependencies.
