Merge #465

465: Fix defmt support r=burrbull a=jkristell

Right now on relase 0.12 (and master) this:
```
DEFMT_LOG=debug cargo build --release --features=rt,stm32f405,defmt --examples
```
fails to compile due to `defmt` support in fugit not being enabled.

This workaround fixes that, but feels like a hack.
It's described here: https://blog.turbo.fish/cargo-features/

The other option is to rename the fugit feature under a different name, but this fix could be used until then.

Let me know if you want this to be merged and I can write a Changelog entry.
