Support for macOS Catalina 10.15.6

Hi! I have a MacBook Pro (Retina, 13-inch, Early 2015) with Intel Iris 6100. I have 4K TV (TCL) too and I use it as my external monitor. The problem is with the refresh rate. The maximum frequency (no matter if it's connected via HDMI-HDMI cable or Baseus mDP-HDMI) is 30 Hz at 4K resolution. I tried to patch the clock with no luck :/

❯ ./CoreDisplay-patcher.command
SIP looks to be disabled, all good!

Unknown version of CoreDisplay found.

When I type:

❯ ./CoreDisplay-patcher.command patch v5
A backup file already exists - If you force this patch on an already patched version you will lose your original backup!
Be careful: Having no working version of CoreDisplay requires you to reinstall the OS.
It might be wise to undo the patch before trying to redo it using: ./CoreDisplay-patcher.command unpatch
Do you want to continue? [Y/n] Y

The code is still the same. Patch seemed to run, but was probably for the wrong version.
If you are running a new OS, run ./CoreDisplay-patcher.command md5 and ask the maintainer of this script to add support for your system.

Could you please add support for 10.15.6? :)
