add macos ear damage warning

[elgiano]

After a request from users on the forum, here is a proposal for adding a warning for ear damage under macos downoad page, with recommendation to install the SafetyNet quark, and a link to Quarks installation instructions.

Forum discussion: https://scsynth.org/t/way-to-limit-maximum-output-volume Issue with CoreAudio not clipping/limit the output range: https://github.com/supercollider/supercollider/issues/4894

I support adding this warning.

I'm not sure what's the best way to go about the quark though - installing a quark is a potentially complicated task (if git is not present; we don't handle that situation well currently, see https://github.com/supercollider/supercollider/issues/3967, https://github.com/supercollider/supercollider/issues/4283 and possibly other issues). I don't know if we have an alternative, but maybe others have ideas about this?

Maybe we can ask @adcxyz to add some installation instructions to his README? Something like:

If you have git: Quarks.install("SafetyNet")
If you don't have git: 
- Download a ZIP from this page
- Extract to a folder
- Quarks.install("~/Downloads/SafetyNet")

I think it would be beginner friendlier to simply list git as a requirement (on osx it's an easy installation + there's plenty of tutorials) and describe how to install the quark through the GUI. e.g.:

1. install git
2. in the UI's top menu go to `Language > Quarks`, find the `SafetyNet` quark and click on the plus symbol. This should install the SafetyNet quark.

Hi, added instructions as suggested: https://github.com/adcxyz/SafetyNet/blob/master/README.md

Great @adcxyz, thanks!

You just have some little formatting things there, if you would like to make it look better:

• need a space between ## and How to install, otherwise the heading doesnt render
• you could enclose sclang commands in backticks to render them as code boxes

thanks @adcxyz !
