version 0.0.4

Hey!

This time I've mostly been busy but I've still got a small update for the pack, here are the changes:

BUGFIXES:

- Changed folder name (from `Unity/Shaders/Include` to `Unity/Shaders/Includes`) to match custom node import paths.
- Made the pattern of the dev shader for Unity scale with the object scale instead of stretching to match the behavior of Godot's version of the shader.

CHANGELOG:

- Added smoothness tweaks on cheese shader for both Godot and Unity, improving overall look.
- Added secondary bigger checkerboard pattern to the dev shader for both Godot and Unity, improving the readability on bigger scale objects.
- Added brushed metal shader for both Godot and Unity!

Have a very lovely evening and I hope this pack is of use to you!
