feat: use slog handler

[injeniero]

Using the handler directly allows to correctly set the Record.PC

This PR also fixes #15

[stevenh]

This fixes the issue raised but also eliminates the benefit of a structure logger as everything is now just a Sprintf.

Is there a way where we can have Info and Infof etc?

[injeniero]

We can do that, but this is targeting GORM lib, and they use their interface as if it was a Sprintf call. It would be on them to extend their Interface and add new methods.

Why would you like to add methods that are not part of the interface?

Would be nice to support a more structured approach, but that would require internal changes to gorm, so I think this is the best that can be done without a breaking change there.
