PEX upgrade to 1.2.11

All - I would like to move the PEX used by Heron to the latest version. The big advantage of this new version is that it allows to generate multi-platform PEX files. Typically, we upgrade by checking in the PEX sources into the Heron repo. This is not desirable since the code needs to be
