OpenVDB depends on OpenEXR as a dependency however OpenEXR does not yet have official binary releases. We've been handling this by building from OpenEXR stage releases until now however since staging repos are deleted every 30 days we have to remember to manually bump every 30 days.

Need to come up with a way to handle this better so that OpenVDB doesn't break every 30 days due to us forgetting to do so.
