fix: delayed loading of the nvim-gps module

[brunuh]

What

Delays the loading of nvim-gps until required

Why

nvim-gps is being loaded when winbar.nvim is loaded, this causes a issue if nvim-gps is loaded after. This is a workaround that delays the loading of nvim-gps

Addresses the issue reported here: https://github.com/fgheng/winbar.nvim/issues/14

Also integrated the seperator typo 😬 (I wanted it to get it into my branch)

@brunuh I have included your fix and mine in my fork. Since this project seems to be unmaintained. I would be happy to continue the work on this project.
