OpenCMR2 1.3.1

Fixes for crashes and memory overruns found by playing the game with random input under AddressSanitizer.

• Fix a crash in the championship's saved stage selection with a driver name longer than three letters: the name was copied into four bytes of the stack. The Rally Challenge results did the same with the computer drivers' names ("A. DRIVER").
• Leaving the service area a second time, after leaving it once without keeping the setup, no longer writes into, and destroys again, the car previews of the first visit.
• Fix memory written past its end: the texts of the championship entry selection, which localised texts make longer than 32 characters, the preview wheel variant of the service area's later slots, and two of the in-race camera offset vectors. The decompilation declared them smaller than the original does; it is corrected there.
• A test that plays the game with random input, through menus, races, pauses, replays and the service area, finds faults like these (tools/monkey.py).

Tested locally on Linux x86-64: the unit tests, the 34 runtime scenarios, and 64 random-input runs of 60000 frames under AddressSanitizer and UBSan, through every game mode, without a crash. Release packages are built and tested by GitHub Actions for each supported platform.
