Aaron Kimbrell 746919b3d2 fix: skip raw terrain chunk data with 64 bit relative seeks ...

Each skip computed an absolute offset as a 32 bit tellg plus a size
product in 32 bit math (colorMapSize * colorMapSize * 4 and friends),
which wraps for large values and can seek backwards. The skips are now
relative to the current position with the size promoted to
std::streamoff first. Offsets are unchanged for every real terrain file,
so this only removes the overflow the TODO asked about.
