PlugInstall Instructions

[Gee19]

I'm not sure if I am misunderstanding the following lines:
https://github.com/RRethy/vim-hexokinase/blob/master/plugin/hexokinase.vim#L11-L15

but after a clean install I still see $GOPATH/bin/hexokinase is not executable error. I've tested this on Ubuntu 20 and debian via wsl2 with the following in my vimrc:
Plug 'rrethy/vim-hexokinase', { 'do': 'make hexokinase' }

This seems to fix it:
Plug 'rrethy/vim-hexokinase', { 'do': 'make hexokinase && cp ./hexokinase/hexokinase ${GOPATH}/bin/hexokinase' }

Maybe this can be handled by the Makefile or the error can be suppressed somehow if it is found in those other locations?

Thanks for your time, love the plugin.
