Tests fail on Windows

[uncomputable]

The library behaves in strange ways on Windows, which makes the unit tests fail. We should fix the code and enable Windows in CI.

See #272 (where Windows was not enabled in CI for this reason)

[apoelstra]

Can you PR to enable windows CI so we have a Github Action output to poke at?

[uncomputable]

Jets seem to outright fail. Maybe this is a C issue.
