HDR lightmaps

To not confuse with adaptative lighting (#29).

It would be cool to implement HDR lighting.

@SomaZ has q3map2 patches to bake HDR lightmaps with q3map2: https://github.com/SomaZ/GtkRadiant/commits/master

Dæmon engine claims to have EXR support. So, we may compile lightmaps with that HDR patch, convert them from RGBE .hdr to EXR .exr and attempt to load them.

XreaL's q3map2 fork also had code to produce HDR lightmaps, writing HDR PNG if I'm right.

For the record, ioquake3's renderergl2 has support for optional alternate HDR lightgrid (loading from external file maps/<mapname>/lightgrid.raw).
