Currently, we request exact clock rates from the firmware to be set with set_rate. Due to some rounding errors and internal functionality of the firmware itself, this can fail. Thus, add some slack to the set_rate functionality so that we are always guaranteed to pass. The firmware always attempts to use frequency as close to the target freq as possible despite the slack given here.
