Installation requires improvisation

[taylorpetty]

I was only able to get the example running after making a few changes not explained in the documentation.

1. There were no compilation instructions. I ran make all within src, which was hopefully correct, but it wasn't clear whether that was the right choice or not.
2. During the install, lib and bin directories were missing from particular locations and had to be created manually (bin within the root dir of the project, and lib within src).
3. While pMDR_manual.txt was helpful, the config file xor.cfg it mentions should be updated to 27.cfg in order for the command to execute.

For reference, I'm using Rocky Linux 9.2.
