Respect upAxis metadata when reading usd about al_usdmaya

[robthebloke]

When you say ignore, do you mean on export? or when importing a proxyshape?
Having looked through the pxrMaya code, the only place that seems to pay attention to the upAxis is when exporting from a maya scene to a USD file. I can't see any obvious place where that flag is tested on import, or within the confines of the proxy shape?

I mean on read / display in a pixar proxyShape. Haven't tested the file import behavior. And not sure how they're handling it - maybe they're enabling some obscure or oddly named flag which enables handling somewhere within usd? - but I know that they bring shapes in so a z-up scene displays in maya "corrected" so y is up.
