I guess the format is  `M49RG20-Qqqyy-aaab.ZIP` where
- `qq` is the quarter of year `{00..04}`,
- `yy` is the year and
- `aaab` i suspect its a map bundle identification (i never saw `d` being other than `1`).

Please leave a note if you have seen more pattern or other prefixes than `M49RG20-Q`.

Note: i have not seen newer maps than Q1 2023 in Q4 2025.
