[Feature Request] Check for and use .zshenv / $ZDOTDIR for zsh installs

Hey there, My .zsh install is not in a standard location, but it uses the standard setup, which includes a .zshenv file within $HOME. In that file, the var $ZDOTDIR is set, which contains the location of the .zsh install and .zshrc file. Checking for the .zshenv and zdotdir var should allow proper installation for folks who are using non-standard .zsh locations. As of now, I try to run the install command and I just get the following:

Pulling down bashhub-client from 2.2.0 branch
No zshfile (.zshrc could be found)

Thanks, -MH
