These decoders have been moved into their own subfolders under the extras/decoders folder: extras/decoders/libvorbis extras/decoders/libopus In addition to being relocated, they have also been split into separate .c/h pairs. They now work like a more conventional library. The implementation of these libraries have also been decoupled from the miniaudio implementation which means they depend only on the header section of miniaudio.h now. With this change the custom_decoder and custom_decoder_engine examples have been updated. To compile these you now need to link in the miniaudio_libvorbis.c and miniaudio_libopus.c files via your build tool. For your own code, you can still include the .c files directly into your code if you want to compile as a single translation unit.

This object can be plugged into any `ma_data_source_*()` API and can also be used as a custom
