Subject: [PATCH] MAINT: Downgrade Opus submodule

Since newer Opus versions appear to cause crashes under some
circumstances, we downgrade our Opus submodule to point to the latest
stable release, which is v1.3.1 from 2019.

We will only be able to upgrade again, once the underlying issue causing
the crashes has been identified and fixed.

Fixes #5302
