docs: adding lowfi to homebrew

[talwat]

I think this is of particular importance, because homebrew is the "primary" package manager on macOS and therefore is used by a lot of people. The project doesn't particularly like maintainers submitting their own software however.

From Homebrew's Acceptable Formulae Guidelines:

We frown on authors submitting their own work unless it is very popular.

So if anyone in this thread thinks they're up to the task of submitting lowfi, then go ahead.

I could try this, I never submitted packages in brew but as my work laptop is a MacBook I need lowfi from homebrew :)
