ok, i'm in a bit of a pickle right now... i have a workflow which automatically flashes an RP Pico using UF2 (no debugger attached). it reboots the pico to bootloader mode (using a `postcard-rpc` endpoint in the firmware) and then loads the firmware on it using `elf2uf2-rs`. this worked just fine (even just this morning!)... except for now:
```
Error: "Unrecognized ABI"
Found pico uf2 disk /mnt/foobar
```

i don't understand this error. i didn't change anything in the firmware project (it's the same exact git tag which it uses which worked before). does anyone have an idea on what i can hunt down for this?
