feat/order: fix order by recently opened, add order by setting

Hello, here is the fix for recent open project sort and order by setting feature.

In my tests this method not worked as expected

M.get_last_accessed_time = function(path)
  local expanded_path = vim.fn.expand(path)
  local fs_stat = vim.loop.fs_stat(expanded_path)
  return fs_stat and fs_stat.atime.sec or 0
end

When project change via plugin the atime of folder not changed so that we always have same time there and projects are not ordered as expected. However if I use GUI (the finder in my PC) and go to the project folder > the atime change. As a workaround I stored the last accessed time in project string. In addition added new setting order_by so that we can order projects asc, desc and recent(default)

Please check if it's ok for you

Thanks
