- Improved LoadBMFont()

Now it accepts a ';' separated list of extensions, useful to check multiple extensions

Get the unicode equivalent characters (as int array) from a UTF-8 text array... maybe this function is renamed to be clearer to users...

When adding alpha mask to GRAYSCALE image, if using ImageFormat(), it could change pixel values, now we avoid that, mask is just added as an extra channel

The result of `success` is actually never used. Either we should check
for it and return or remove it. I assume just checking the last one is
okay.

* Const corectness for LoadShaderCode

* Added const for standalone variant as well.

Still looking for a better way to integrate it into raylib API, maybe add a LoadImageAnim()?

Note that latest emsdk changed paths

- ADDED: CompressData()
 - ADDED: DecompressData()

This reverts commit 53b32f1c20.

Replaced DEPRECATED functions

...moved to internal AudioBuffer structure as totalFramesProcessed, now time measure works again... but there is some problem with looping...
Also note some inconsistencies between frames and samples, it seems those concepts are not considered correctly in the code.

raylib logo animation has been removed. That funtionality was very restrictive, not configurable at all and hardly ever used, also, it added a coupling dependency of `core` module with `shapes` and `text` modules.

All data should be properly initialized by now

It appears that you've missed renaming this function here, which makes trying to compile standalone raudio.c error out.

Some generated fonts were not fitting the image...
