Bump version

Changes:

* Optimize panic handlers

  panic_handler_crash now sidesteps additional error reporting that may
  have been possible depending on the interrupt state.

* Add support for embedded-nal-async 0.7
* Gcoap: Fix building on 64bit platforms
* Inspect BINDGEN_OUTPUT_FILE instead of linked riot-sys environment
  variables at build time
* Don't use custom rustfmt configuration
