BL Demo enviro.dat info

Burnout Legends Demo: "enviro.dat" Garage
Initial reads and most operations occur on function i0x089FECF8
File header size = 0x01D0

Notes:
- Only values with prefixed types are confirmed, other are placeholders.
- 4-byte values are assumed to be u32/uint, but may be s32/int instead
- Values with no decriptions mean that the value is re-stored as-is somewhere in RAM.
