Hex string highlights invalid non-hex characters

[wesinator]

Current basic hex string regex highlights any characters between = { }

Expected: only highlight valid hex string chars a-fA-F0-9?
This will help with identifying invalid strings in rules

@wesinator ... and 2 years later I believe this has been fixed. I'll be adding this to release 1.6.0 after I attempt to apply the same logic to address issue #28. In the meantime, if you get around to it can you take a look at the screenshot in the linked PR and let me know if that is or is not what you're looking for, please?
