implement workaround for table edge issue

[Yurlungur]

PR Summary

As discussed on mattermost, implements a fix for the discovered issue where for some inputs within machine precision of the boundary of a table, eospac produces incorrect output.

While we haven't yet figured out what is going on (I'm working on a self-contained reproducer), I argue that this change is harmless and avoids the issue, so we should move forward with it in sesame2spiner.
