[FEAT]: Clickable directory Entries

[thattomperson]

Requirements

• [X] This feature isn't just a vague idea and can have a good practical solution.
• [X] I'm completely sure that this feature fits into this plugin.
• [x] I'm willing to implement this through a PR.

Problem

It would be nice to be able to click on the directories and have a callback fire

an example use-case would be to open nerdtree or oil.nvim to that directory

Solution Suggestion

adding an additional onClick to the Entry class should be simple, I'm not sure how you would want to implement it though

the current to = {} stuff could be made generic to to use the same click handlers with a default implementation

configuration could be done pretty simply with a table

function Entry:navigate()
  local handler = config.onclick[entry.type] or function (entry)
    vim.cmd.mark("'")

    vim.api.nvim_set_current_win(entry.to.win)
    vim.api.nvim_win_set_cursor(entry.to.win, entry.to.pos)
  end
  handler(self)
end

require('barbecue').setup({
  onclick = {
    dir = function (entry) 
      require('nerdtree').focus(entry.filepath)
    end,
  }
})

some additional parameters would be required on the Entry to make this useable, like the filepath one above
