merge some light algorithms together
allow changing attenuation on surface lights with _surflight_atten
replace some emplace_back's with push_back to improve compilation times
* light: Add support for LIGHTING_E5BGR9.
This is not really finished. Currently mutually exclusive with
regular RGBLIGHTING, and not tested with external .lit file.
* light: replace HDR_PackResult with a version following the OpenGL spec
- add HDR_UnpackE5BRG9 for unpacking
- caller is now responsible for scaling 128 -> 1
- expose in header for tests
* light: move HDR_PackE5BRG9/HDR_UnpackE5BRG9 to common/litfile.hh
* build: std::powf not available in gcc
* common: move LoadLitFile to litfile.hh
* common: LoadLitFile: return hdr variant as well
* lightpreview: add an Exposure slider
* lightpreview: support hdr .lit's, wip
* tests: refactoring to set up testing for hdr lit's
* tests: add test for -hdr and -bspxhdr
* tests: fix LM_Sample to deal with styles correctly
* lightpreview: fix glsl error
* lightpreview: show dialog box for glsl compile errors

previously, we were writing a json dictionary which was confusing
- bspfile: fix reading a valid texture followed by a missing texture
(offset -1)
- add missing texture testcase
use stb_image_write for PNGs for better compression on bsp.json
add in code for spitting out a lightmap from a face. doesn't support other styles and such yet.
- for Quake-likes, WADs will be added as file system archives directly when the first brush is encountered since the wad key is ready to go by that point.
- after loading the .map and before constructing the BSP, what I call secondary textures (animation frames for Quake-likes) are added to the list, and the BSP's miptex data is filled.
- BSP miptex data is now opaque to the BSP process; the BSP simply copies the raw miptex information from the input. This simplifies the BSP structures and reading/writing routines.
- the img subsystem supports reading from raw miptexes now, although in practice this only happens for Quake-likes atm
- instead of a "wal cache", maps now have a "meta cache" which stores the metadata information for all games instead of just Quake II
- texture meta can now be ref'd out rather than needing to be copied every time (mainly only a gain for the std::string)
- wad.cc/wad.hh is gone; wads are now pushed into the filesystem archive
- fixed broken wad_archive
- fs subsystem iterated on a little bit; supports marking archives as external (only used for wads currently; see `LoadTextureData`)
- load_tga has better error handling
- add in foot-gun protection to the BSP readers; now they assert on failure to read instead of silently propagating that error throughout the rest of the process
- bsputil uses img stuff now, so it should handle palettes better
support for radiosity _surface lights with `_surface_radiosity` key
allow lightstyles for _surface radiosity lights
bounce enabled by default on Q2
remove ValueForKey, use epairs directly
remove byteswap as it wasn't used any more
re-introduce imemstream and omemstream to make it harder to accidentally use the wrong operators
add dynamic padding stream manipulator
use memstreams for BSPX
