Make Silo Reader Handle Overlink Databases that are NOT in Symlink Format

[JustinPrivitera]

This is possible, it just requires mucking with paths. The right behavior would be triggered if the root file's name is OvlTop.silo. I have logic that handles this case in the Silo Reader inside Conduit.

@JustinPrivitera any chance you can attach an example database here or maybe give me one on RZ/CZ?

Here are a whole bunch: https://github.com/LLNL/conduit/tree/develop/src/tests/relay/data/silo/overlink

There are symlinks there as well. I am proposing we add support to read directly from the files called OvlTop.silo in each of the directories. But I don't know whether or not that is a good idea 🙃
