Add casing to from_dict method

### Summary

from_dict method did not support casing

### What is the feature request for?

The core library

### The Problem

When using `to_dict` method I can pass case, but for `from_dict` method only safe_snake_case is available, It looks like some inconsistent behavior

### The Ideal Solution

As i understand `safe snake case` is not necessarily needs to be safe, so replacing it with any casting method would be safe

### The Current Solution

Just use snakecase in dict

Start by locating the core library entry points for from_dict and to_dict, then compare how the existing case argument is handled by to_dict with the fixed safe_snake_case behavior in from_dict. Confirm the intended casing options and identify the relevant tests or test location before defining done as consistent casing support for both methods.
