[TPHD] Add bloom graphic pack

[KoB-Kirito]

Based on the work of @skalfate - #508 (comment)

I tinkered a lot with the values, tested them in different areas of the game and condensed them in useful presets.
Changing the bloom improves this game so much, it should be available to everyone!

Changes the bloom in the game, which is used aggressively in the shadow world, where it has a strong yellow cast. Can also remove the yellow tint by shifting the bloom color to blue. A too high value can cause a blue cast outside of the shadow world. Up to 50% is safe.

Here a comparison.
