genstructs.py: refactor; use match/case statement

Browse Source 
- lol, i had no idea python *FINALLY* added a switch/case equivalent.
sadly though, it looks like the generated python bytecode is
nearly identical in performance.
there's no lookup table magic for match/case, and is almost
identical to if/else if/else. it amounts to syntax sugar 😭
