Set maximum of allowed keys pressed simultaneously #1532

I'm currently in the process of modding a Logitech K380 with a custom PCB and firmware. Logitech has pretty much cheaped out here and have a key matrix without any diodes on it. They work around this by wiring up the key matrix in very unexpected ways (i.e. column 17 is connected to f4, 5, 8, tab, t, g, x and up) which seems to make ghosting less relevant in normal use.

Additionally to prevent ghosting effects, the Logitech firmware will not register more than 3 keys at a time. Would something similar be possible using ZMK?

I've developed a simple proof of work to fix this issue in #1533
