Feature: Add slog compatibility layer

[flimzy]

I know this project is in maintenence mode, but I think it would be worth making an exception to the "no new features" rule to add a simple slog compatibility layer, as the alternative is some minor chaos when others create competing implementations, and inevitably abandon them.

This could take one, or even two, forms:

• A slog hook for Logrus
• A Logrus handler for slog

I would be happy to take this on and write the code (I have a partial implementation already completed for a client I'm working with).

Would love to see this accepted in core logrus also.

I've begun work on this, and intend to create a PR before too long.
