[TPHD] Add new Bloom graphic pack (#642)
With the new bloom graphic pack you can simply choose a preset of the amount of bloom and brightness/post-processing inside the shadow land, or you can fine-tune it to your likings with the custom options.

Thanks to @KoB-Kirito for making this dedicated bloom pack!
