Update HAL and cortex-m dependencies

[robamu]

Hello,

Thanks for providing this board crate, it was very useful to quickly get started with OpenOCD and VS Code on my STM32F3-Disco :+1: There are newer versions available for some of your dependencies. I updated them and tested this on my STM32F3-Disco. The only thing I tweaked (which was not a breaking change) was replacing a deprecated API, using into_af_open_drain instead of into_af4_....

Bumping the dependencies like this probably requires a minor version update, so I did that as well..

Kind Regards Robin

Thanks! I always run the examples on hardware before merging, so it may take me a few days to merge, but I’ll absolutely do that sometime over the holidays.

I’m glad you found this crate useful and can’t thank you enough for updating the deps.

Cool, take your time :)

Any chance this can be committed and released soon, I would like to use later version of stm32f3xx_hal
