Conda-forge staged-recipes (Build win_64 win) job failed with pyzbar >=0.1.9 dependency

[vmdocua]

While onboarding reprostim project to conda-forge (Add reprostim PR), we observed error in "Build win_64 win" job. It reports error regarding zbar like listed below during build/test actions on Win64. As temporary bypass we switched to v0.1.8. Please advise.

Encountered problems while solving:

- nothing provides zbar needed by pyzbar-0.1.9-pyhd8ed1ab_1



Could not solve for environment specs

The following package could not be installed

\u2514\u2500 pyzbar >=0.1.9 * is not installable because it requires

\u2514\u2500 zbar =* *, which does not exist (perhaps a missing channel).

##[error]Cmd.exe exited with code '1'.

Yep, pyzbar needs zbar, which is not presently built for windows.
