feat: add types and fix minor bug

[shadowgate15]

First and foremost this adds TypeScript types.

Second, I noticed a minor bug in making sure that all necessary methods on the logger was set to functions. If a logger was passed in with a field of 'log', for example, that was set to a non-nullish value but was not a function, Axe could attempt to set another required field to that value. This causes errors when that function is needed.

@titanism it looks like xo version 0.57.0 bumped to require node 18. How would you like to proceed?

[titanism]

I will require node v18 and major bump

[titanism]

Actually, just will stick to v0.56 for now.

[titanism]

I think we need to add to files the types
