Causes crash when you don't have Pygments installed #1
Description
Currently when you don't have Pygments installed, using SwiftPygments will crash.
Fatal error: 'try!' expression unexpectedly raised an error: Python exception: No module named 'pygments': file PythonKit/Python.swift, line 674
It would be great if it could use attemptImport and try?, and throw the resulting errors down to the user of the library, so errors can be caught and presented to the user, instead of crashing.
I'd love to include SwiftPygments as a dependency in my static site generator library, but I think it would be a lot better if import failures were handled gracefully 😅
