Lazy Load Plugin

[camin-mccluskey]

Thanks for this fantastic plugin! I noticed that, copying the setup (using Lazy as a package manager) in the README, the plugin never loaded. I've "solved" the issue by adding lazy = false but ideally it would load on the correct event. Could you suggest the appropriate event to ensure the plugin is loaded only when necessary for renaming/moving (cutting and pasting) the file in nvim-tree? Thanks

Hey! I personally still haven't found time to migrate and using packer. So not sure what are these events. I know that nvim-tree dispatches internal events. And we can register callbacks to handle them. https://github.com/nvim-tree/nvim-tree.lua/blob/master/doc/nvim-tree-lua.txt#L2328

This setup was added in #20 and I just assumed it works. @jellis206, could you please take a look if you have time?
