Extremely long warning

[jakobjpeters]

I have some generated code that substantially exceeds the RECURSION_LIMIT, overwhelming my CI log:

┌ Warning: default_param_context reached recursion limit
│   leaf = ExplicitImports.Vendored.AbstractTrees.ImplicitCursor{...}

It would be nice to improve the warning so that it wasn't so verbose, perhaps only being so verbose with debug-level logs? I'm not sure on the implementation details, but #171 may also provide a way to prevent this warning in the first place by excluding offending files.

As it stands, I have to pin ExplicitImports.jl to a version pre-dating the RECURSION_LIMIT until this is fixed.
