fix: Issue 227 - Named Creatures of same type append 1

[NDomergue]

Pull Request Description

Fix Issue 227 where in the Encounter Tracker, named or not named Creatures had a counter next to their name based on their underlying type (Gobelin, Hobgobelin, etc...) instead of their actual name (John Doe, Foo, Bar...).

Changes Proposed

• Modify the algorithm in setNumbers to compare distinct names (display or not) instead, by using a Map to compare them
• In both tracker.js/doUpdate, use Creature.getName() instead of re-doing the same algo that ignore the Creature.display attribute. I guess it affects the logs? I think it would be easier to read with the actual display name instead of the generic name. But I didn't check that part really, what do you think?

With the changes, here is the tracker : As you can see, the first of each distinct name has no numbers, then we count 1,2,3...

Additional Notes

My main goal was to discover your code by trying to fix something easy.
My main goal after that is to implement the rules specific to the TTRPG TheOneRing to track combat.
That's my first contribution to an OSS and also my first PR in GitHub (although I'm working as an experienced SE, but mainly in C#), so do tell me if I did anything wrong.
