Skip Display Check on MacOS m1 so custom comamnd can run regardlessly

[lazywei]

This is based on haimgel/ddc-macos-rs#2 (comment). A futher improvement can be made to use m1ddc as external command to gather display info.

Thanks, I was able to get it working on my m2 mac with this PR.

Instead of m1ddc I used Lunar (as I already have it installed) with this config:

usb_device = "1a40:0101"

on_usb_connect_execute = "lunar displays external input displayport1"
on_usb_disconnect_execute = "lunar displays external input hdmi1"
