bindgen CI failing on Windows

[Mytherin]

The bindgen CI is failing on Windows with the latest v1.0.0 build. I've disabled the CI run for now, but this should be looked into as this could indicate problems for the Windows release. Here is an example failing CI run

Pre-v1.0.0 these bindgen tests did not exist as can be seen in this CI run. For some reason bindgen has added extra tests after the port to v1.0.0, that then failed. Perhaps there is some configuration that can be set to disable this behavior. bindgen itself seems to have lacking support for Windows so this may well be an upstream bug that we are running into that we were not running into before due to some change in our C API between the two versions.

We could also consider whether we should be using bindgen anyway - given that our C API is not particularly complex. For the Julia client, for example, we don't use a library and generate the bindings ourselves.
