Create Programming Data Rate Functions

[kb1lqd]

For mainly testing reasons I'd like to create the functionality in the initial release to program various transmit data rate options. Respective receive bandwidth filtering should also follow suit. I am focusing on FSK/GFSK.

Goals

• Provide a set of standard baud rates to choose from
• Configure both TX and RX

To properly sync receive data the CC1101 radio core bandwidth should match the expected.

Baseline 38kBaud

I've been developing Faraday's firmware using a standard 38kBaud since it is relatively fast and sensitive enough. Here is the SDR spectrum observed (not very sciencetific!)
