[Bug] Occasional “F22” key appears, and won't disappear.

[EvenZHAnglll]

Describe the bug
There is a "F22" key shown in the bar, and won't disappear.

Version: v1.0.6

To Reproduce
After trying, I found a way to reproduce exactly. It's related with WeChat client on Windows.

1. run the keyviz
2. login WeChat windows client
3. "F22" key shows up

Expected behavior
Regardless of whether it is a bug caused by WeChat app, the “F22” key should not appear. Because it is not a key.

Screenshots
The "F22" appear.

Desktop:

• Windows 11

I did some research and found that some old-fashioned keyboards do indeed have an F22 key. F22 is an actual key.
But now, general keyboards only have F1 to F12 and do not have F13 to F24.

The reason for this bug seems to be due to WeChat, not keyviz.

But this frequently occurring F22 is really annoying. Maybe an option can be added to not display F13 to F24 Key.

Indeed old keyboards had keys from F13 to F24 and there is keymapping for the same as well -

keyviz/lib/data/keymaps.dart

Lines 79 to 104 in 79905cf

	final Map<String, String> functionKeys = {
	'F1': 'F1',
	'F2': 'F2',
	'F3': 'F3',
	'F4': 'F4',
	'F5': 'F5',
	'F6': 'F6',
	'F7': 'F7',
	'F8': 'F8',
	'F9': 'F9',
	'F10': 'F10',
	'F11': 'F11',
	'F12': 'F12',
	'F13': 'F13',
	'F14': 'F14',
	'F15': 'F15',
	'F16': 'F16',
	'F17': 'F17',
	'F18': 'F18',
	'F19': 'F19',
	'F20': 'F20',
	'F21': 'F21',
	'F22': 'F22',
	'F23': 'F23',
	'F24': 'F24',
	};

The same have been reported in #102 as well. And maybe it's related to #56, #88.

But as mentioned, modern keyboards don't have F13-F24. I should opt out the same. And also set a mechanism that detects visualizations that doesn't disappear and remove the same after an interval.

But as mentioned, modern keyboards don't have F13-F24.

Just as a sidenote, F13-F24 is often used in laptops where for example something like Shift/FN+F[x] may trigger a keypress for F[x+12] (or other way around if fn-lock is toggled), so they are not completely obsolete.
