Add a function to return all supported standard baud rates for the port about serial-rs HOT 2 CLOSED

I'm not aware of any API that returns supported baud rates for a serial port. That information usually comes from reading the hardware's datasheet, and then it's usually determined by a base clock frequency and a divisor with some simple formula for calculating the final baud rate. The best such an API could do is provide a guess as to what's commonly supported. This library has done that via the BaudRate enum.

I think you misunderstood what I meant. I'm not trying to have this library reach into the hardware driver and extract actual supported baud rates, I wanted to get a list of standard baud rates for the current platform. The baud rate enum is dependent on the platform as to what standard rates are supported, for all others you need to use BaudOther. It'd be very helpful to be able to easily get a list of those standard rates.
