v1.12.1 on 2023-04-06: Serial read in PChem (v1.12)
DEPRECATED. USE v1.12.2 if you need a v1.12 tag.
This is a zero-diff patch to v1.12.0 where the parallel read of the PChem species file was removed leaving just the serial read-on-root-and-broadcast.
This was done due to issues encountered at NAS reading on many nodes.
