Contributed simple shader example

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

Note that latest emsdk changed paths

Note this example is not working properly, it still requires some review.

- 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.

I'm not sure why the clean command is so complex (especially given that find -type f -executable | xargs rm -fv works!)
but I fixed the version as is, to support x-pie-executable which was preventing it deleting anything on my system...

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

They are not automatically unloaded when unloading the model!

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...
