Add zgenom installation support

[V4G4X]

Feature description

Among the zsh plugin manager, zgenom is not supported. And I am having trouble installing with it.

Cloning into '/Users/varungawande/.zgenom/sources/luismayta/zsh-notify/___'...

-- zgenom: Creating `/Users/varungawande/.zgenom/sources/init.zsh` ...
-- zgenom: Compiling files ...

Why is it needed?

It's a fast and popular plugin manager for ZSH.
