Update libsndfile to 1.0.30

[tchagnon]

libsndfile 1.0.30 was released on Sep 19, 2020. Could you updated to include the latest release of the lib? There are a number of bugfixes and improvements. https://github.com/libsndfile/libsndfile/tags

In particular, I'd like to pick up this fix for slow sf_seek(). libsndfile/libsndfile#491

PySoundfile depends on these binaries as a submodule: https://github.com/bastibe/SoundFile

Thanks for opening this issue!

I've just created a PR for mxe: https://github.com/mxe/mxe/pull/2587. As soon as that is merged, I can create the DLLs for Windows.

I currently don't have access to a Mac, so I can't create the .dylib. I hope somebody else can provide a PR for that (please note the added opus dependency!).

I could provide the .dylib for mac. Do you think the instructions in the README are up to date? I can look into it.

That would be great!

The libsndfile download location has changed to https://github.com/libsndfile/libsndfile/releases/download/v1.0.30/libsndfile-1.0.30.tar.bz2.

There is now an additional dependency to the opus library.

And I think those version can be updated:

flac-1.3.3
libogg-1.3.4
libvorbis-1.3.7

Other than that, I think it is up to date.

I figured it out. The Flac build was failing due to some bad uint types in the ogg headers. I was also able to test that it's working in the SoundFile repo with python setup.py test while pointed at my local branch here.
