Creative HD Material Pack - Minecraft with RTX

Additions:
- Added 8 new statically-colored colored glowing blocks, inspired by glowing blocks shown in early Minecraft RTX demo footage (with hexagonal fading edges)
Purple, Magenta, Brown-ish Orange, Red, Yellow, Green, Blue and Cyan colored are included, > These blocks occupy element 104 (Rf) through 111 (Rg)

- Added two "Vanilla RTX" blocks, one static, the other periodically blinking, a reference to Vanilla RTX App, but also a nice decorative block! It features a 8x8 redstone-lamp inspired texture, the blinking one can be used to get compact blinking lights without having to do redstone!
> These blocks occupy Element 102 (No) and 103 (Lr)

Blocks are named appropriately for US and GB English, just search "Vanilla RTX" and "Glowing" to get them!

Other Changes:
- Revised POM data (blue channel) of several normal maps (Parallax Occlusion Mapping is used when using the appropriate BetterRTX 1.5+ preset)
- Downscaled several textures that could continue to look good at a lower resolution, to make space for newer textures
- Updated PBR texture formats to include the subsurface property.
