A TODO asks to convert the bit_rate variable to be a u32 so that bit
rates up to 300kbps can be supported as per the spec.

* currently the code introduces new IOCTLs. I'm afraid this is a bad idea.
-> Replace this with another interface, hints are welcome!
* Some missing data (marked with ###) needs to be added in the documentation
-* Change (struct pi433_tx_cfg)->bit_rate to be a u32 so that we can support
- bit rates up to 300kbps per the spec.
