Is your feature request related to a problem? Please describe.

I forgot to switch the XOR key input field from hex to UTF8. Ideally, CyberChef would have warned if the input contains non-whitespace, non-[0123456789abcdef] inputs.

https://cyberchef.org/#recipe=XOR(%7B'option':'Hex','string':'Why%20is%20this%20allowed'%7D,'Standard',false)&input=U29tZSB0ZXN0IHN0cmluZw

Describe the solution you'd like

A warning or something would be nice to see

Additional context

Wasted like 2h in flare-on because of this 🙃

Hello, I would like to attempt to fix this issue. I looked through the changes in #1975 and it seems relatively simple to alter the xor to give a warning when there are non-hex characters in the hex input. I think this would help alleviate some of the confusion that led to this issue.
