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
