Updated MonitorControl to the latest version (if applicable)

Describe the issue

Thanks to MonitorControl for this great software and the developers who developed it. I just recently purchased an LG C2 TV for my Mac monitor, and it's realistic, but MonitorControl can't control the LG C2's screen brightness and volume, seemingly because of DDC, which seems to be set up on LG TV's through a network connection

Expected behavior

Correctly adjust the screen brightness and volume

Anything else?

Environment Information (please complete the following information)

- macOS version:12.4
- Mac model:M1 MacBook Air & Hackintosh(intel 12700,MSI B660M,AMD RX550 LEXA)
- MonitorControl version:4.10
- Monitor(s):LG C2 42
- Monitor Cable(s)/Connection(s): Lenovo HDMI 2.1 Cable
- Apple Silicon/M1 (yes or no): yes

@waydabber commented on GitHub (Jun 14, 2022):

Most TVs do not support DDC. They can change their brightness and volume via IR remote only or some proprietary (sometimes open) network control stuff utilized in the TV's remote app. It might be possible to start implementing these in MonitorControl but that is certainly off-scope for now.

I'll convert this one into a discussion, maybe somebody can contribute towards this.
