Support asdf-based fzf installs

[DWSR]

As an ASDF user, I prefer to install all my tooling through asdf. This plugin looks for fzf in a hardcoded location (~/.fzf) which causes a duplicate installation of fzf.

Where does asdf install it?

[DWSR]

In a path based on the version of fzf that is currently selected.

/Users/brandonmcnama/.asdf/installs/fzf/0.27.3/bin/fzf

It looks like this plugin looks in a couple of hardcoded locations only (based on

fzf-zsh-plugin/fzf-zsh-plugin.plugin.zsh

Line 37 in 5758b65

# Determine where fzf is installed

) Is it possible to infer the location of key-bindings.zsh based on the path of fzf?

That will make it easier, thanks.
