Hash/Check 4+

Not a whole lot new in this version. Found a few things that were bugging me, and as this is just a side project - I fixed them! For one, why just Green and Red for good hash/bad hash? Seems a bit holiday specific or may traffic light specific. So this update adds a Blue/Orange or Brown/Purple option! Also really kinda small, but the "File Location" path now shows a tiny icon of what kind of Mac you're using (thank you SF Symbols!), including the Trash Can Mac if you're still running with that beast. Um... What else... There is still a few UI refresh bugs that I can't seem to quite track down yet, but I'll get there. Anyway, be kind, be nice, be good.
