Separate filter type and decimation rate from the sampling frequency

See related comments in my reply to the documentation patches about wideband vs.
FIR and decimation rate vs. -3dB cutoff.

Previously, combining decimation and MCLK divider in the sampling
frequency obscured performance trade-offs. Lower MCLK divider
settings increase power usage, while lower decimation rates reduce
precision by decreasing averaging. By creating a decimation attribute,
users gain finer control over performance.

It seems like we would also want a power_mode attribute. We already have an
attribute for this for used by accelerometers so there is some precedent for
such an attribute.

The addition of those attributes allows a wider range of sampling
frequencies and more access to the device features.
