[Seisunix] Announcing Incremental release 44R28 of Seismic Unix

This release does contain a fix for the “types.h” (tirpc) installation problem seen by users on Ubuntu 22.04. I have also started adding platform specific installation instructions on https://wiki.seismic-unix.org https://wiki.seismic-unix.org/ under Documentation. Right now this includes a list of all the packages that you need to install under Ubuntu 22.04 before you can install SU.
