fix: add validation for RGB/BGR color values in Color class

[Shriya613]

 ## Description
 This PR adds validation for RGB/BGR color values in the `Color` class to ensure they are within the valid range (0-255).

 ## Changes
 - Added range validation (0-255) to `Color.from_rgb_tuple()` and `Color.from_bgr_tuple()`
 - Raise `ValueError` for invalid color values with descriptive error messages
 - Added comprehensive tests for both valid and invalid cases
 - Updated docstrings to document the new validation behavior

 ## Testing
 - Added test cases for valid RGB/BGR tuples
 - Added test cases for invalid RGB/BGR tuples (out of range values)
 - All tests pass

 ## Related Issues
 Fixes potential issues where invalid color values could cause unexpected behavior in annotators.
