Notes for coinor-osi - reproducible builds result

Version annotated: 0.106.9-2
Identified issues:
Identifier: graphviz_nondeterminstic_output
Description graphviz appears to use a non-determinstic algorithm to optimally lay out
notes optimally. This can appear in class hierarchy documention, etc. Can
presumably affect images of all complexity but, obviously, more likely to
affect images with lots of nodes.
