byo_gui_gl crashes on macOS because of incompatible shader version #32

Currently I get this error on macOS when I compile the byo_gui_gl example:

[ERROR] nice_plug::wrapper::util: thread 'main' panicked at 'ERROR: 0:1: '' : version '130' is not supported
ERROR: 0:2: '' : #version required and missing.
': examples/byo_gui_gl/src/lib.rs:105

My system runs the OpenGL version: 4.1 Metal - 89.4, and the GLSL version: 4.10. Which is incompatible with version '130' defined in gl.shader_source(shader, &format!("{}\n{}", "#version 130", shader_source));.
When I change it to gl.shader_source(shader, &format!("{}\n{}", "#version 330 core", shader_source)); the plugin compiles successfully on my system.

Now the issue is; how can we handle different OpenGL versions properly?

I added shader version detection to the byo_gui_gl example in #33 to hopefully fix the issue. (I used egui as a reference for how it does it.) Let me know if it works now!

Or is the gain_egui example failing as well?

It works now!
And to be clear; I had no issues with the gain_egui example on my machine.
