[Feature] built-in `DeepObjectMap`

[valentinhttr]

Hi,

Clear and concise description of the problem

I'm currently using objectMap to transform all empty values to null, but it's not recursive by default.

Suggested solution

This feature request proposes a second deepObjectMap method that would work with nested objects.
