Blake Latchford 8d2a5657ac Pin Radiolab for stm32 and replace ltoa 
The major rev from 19.x to 20.x breaks Radiolab, so pin it for now. This should fix the failing wio-e5-mini_repeater builds.

ltoa is removed upstream, so it was replaced with snprintf. The p[] buffer is always 16 bytes. Copy/paste for why claude thinks this is fine below, but also if this is broken it wouldn't be new.
```
exp2 in [23, 30] (int_part = mantissa << (exp2 - 23)): this is where int_part can reach its true max, up to 2,147,483,520 — 10 digits. That's what the snprintf bound of 11 (10 digits + NUL) is sized for. But in this branch frac_part is never assigned anything other than its initial 0, so only *p++ = '0' runs for the fraction — 1 char, not 7.

exp2 in [0, 22] (int_part = mantissa >> (23 - exp2)): this is the only branch where frac_part can also be nonzero and enter the 7-digit loop. Here int_part < 2^23 by construction, so it's capped at 7 digits, never 10.
```
