feat: call init process before telescope loading (#234)

* feat: call init process before telescope loading

Fix #231

This changes enable to load frecency without telescope's loading itself.
This is needed when you want to load telescope lazily, but want to start
registering process as soon as Neovim has started.

```lua
{
  "nvim-telescope/telescope-frecency.nvim",
  main = "frecency",
  ---@type FrecencyOpts
  opts = {
    db_safe_mode = false,
  },
},

{
  "nvim-telescope/telescope.nvim",
  -- `cmd` opts makes lazy.nvim load telescope.nvim lazily.
  cmd = { "Telescope" },
  config = function()
    local telescope = require "telescope"
    telescope.setup {
      extensions = {
        other_extension = {
          foo_bar = true,
        },
        -- Here you need no configuration opts for frecency because
        -- you've already done.
      }
    }
    -- This is still needed.
    telescope.load_extension "frecency"
  end,
},
```
