Checklist

I have searched for existing issues
I have looked through the wiki
I have updated MonitorControl to the latest version

Describe the bug
Brightness control is triggered by F14 and F15 keys, even when these shortcuts are disabled in MacOS control panel.
This even happens when those keys are remapped to by Karabiner Elements.

To Reproduce
Have an Apple Keyboard with keypad (and therefore F13-F19 keys)
Go to Mac Control Panel --> Keyboard
go to tab: Shortcuts
left select Monitor
disable increase/decrease monitor brightness (or change their shortcuts to some other keys)
press F14/F15
see brightness still be adjusted

Expected behavior
Don't use F14/F15 for brightness control unless they are actually in use for that.

Additional context
This bug is a problem when these are actually used for something different. I need them as "scroll lock" and "pause" for remote work over Windows RDP. Yes, I actually need them many times in a day. Yes, I might be a dinosaur.

Besides that: huge f-in kudos for this app!

Environment Information (please complete the following information):

macOS version: 10.14 (Mojave)
MonitorControl version: 2.1
Monitor(s): irrelevant (but they are 2x Dell S2721DGF which absolutely rock)

Addition: it seems that the issue is not actually specific with the F14/15 keys, but with the "scroll lock" + "pause" function..? I've just remapped F18/F19 for that purpose in Karabiner and bam, they too now control the monitors' brightness.
