This commit adds two new files: `hologram.lua` and `hologram.lua`. The `hologram.lua` file contains the configuration for the `hologram.nvim` plugin. It is responsible for setting up the plugin and linking it to the `absolute.after.hologram` file. The `hologram.lua` file contains the implementation for handling image previews using the `hologram` and `image` modules. It sets up autocmds to trigger the `handle_image_preview` function when entering or opening a buffer with an image file. The function creates a new image object and displays it for 5 seconds before deleting it. There is also a `handle_image_preview_close` function that is triggered when leaving or closing a buffer with an image file, but it is currently commented out. These changes were made to enhance the functionality of Neovim by allowing users to preview images within the editor using the `hologram.nvim` plugin.
