Hi, would it be possible to make the user warnings display only when using pipes that actually depend on these imports? Or at least display them in a way that allows filtering out (with logging package perhaps)?

It's just a minor flaw on otherwise great package. Awesome work!

Is your feature request related to a problem? Please describe.

Since dropping python 3.5 #142 the pandera code-base can now use f-string formatting for conciseness and ✨ elegance ✨

Describe the solution you'd like

• replace all instances of '%s' formatting with f"{}" string formatting
