Integrate Pherim's Redoran mesh fixes

[C3pa]

This was posted by Pherim in the MOP's Nexusmods' comments section. Currently, this comment is on the page 5:

The archive also includes some meshes, namely doors, already covered by MOP, and also smooth models for Redoran exteriors. For historical purposes, I've also attached the unmodified archive: Redoran Mesh Fixes.zip. Here is the description that comes in the archive:

This mod corrects many errors in the meshes of the Redoran tileset, both interior and exterior, including some that are not actually used in the game or only in testing cells, in case they are used by mods. The original models have a lot of distorted or fractured textures, which becomes more obvious with high resolution textures. This mod fixes most of these errors and aims to eliminate distortion or seams where possible. I also corrected irregularities in the geometry and the vertex color, improved the collision meshes and much more. Because the uv maps are now mostly continuous and not fractured into many separate islands, and because I deleted unnecessary parts of the collision meshes (duplicate vertices, uv maps, vertex color), most of the files are now a lot smaller in size, while looking much better. This may or may not improve performance and/or reduce loading times (although I doubt that it really makes a noticeable difference, in most cases).

The models should be compatible with all Texture replacers, and in fact looks best together with HD textures. It is incompatible with all mods that edit the same meshes, for example Lougian's Redoran Bump Mapped (if someone wants to make a compatibility patch, go ahead, but I am probably not going to do it).

There are also optional smoothened versions of most exterior models included, which of course have all the fixes of the default meshes. There is no non-smoothed version of the Manor District/Skar exterior, though, because I started with that and didn't want to do it all over again when I decided to include non-smoothenedd exterior meshes with just fixes. The smoothened version is installed by default, though. It also comes with improved collision geometry for the roof, so you can no longer get inside some of the bulges.

Also included are smoothened versions of the wooden platforms and suspension bridges inside Skar. These are also found in several caves throughout the game, and they are now in my "Improved Cavern Clutter" WIP mod as well.
