feat(lualine): add more hl options to pretty_path (#2687)

* feat(lualine): add more hl options to pretty_path

Adds two additional options to pretty_path: filename_hl and dirpath_hl.

This allows users to customize the highlight group of both the directory
component of the path name and the filenname independently. modified_hl
is still used when the buffer has been modified.

Thanks to dpetka2001 (Iordanis Petkakis) for the changes to the format
function.

* feat: cleanup
