This patch introduces a new build tag `nolibopusfile` that conditionally compiles out the code that imports `libopusfile`. This enables a static binary build on Alpine Linux, which doesn’t have a static `libopusfile`. Tests still work: ```sh go test -tags nolibopusfile ./... go test ./... ``` We could also have moved all libopusfile related code (i.e. Stream) into a separate sub-package, but that would break backwards compatibility. This feature is too unpopular to justify introducing a new major version. See also: https://github.com/hraban/opus/pull/24
