Hi. Is this still draft?

Nope, just updated it.

The right bitgrowth to avoid overflow is calculated by using the maximum
decimation rate. It is more intuitive to use this directly instead.
Decimator_strober now uses the "maxrate" generic to define the
counter width.
Add a wrapper for the cic_decim module and the decimation strobe. Also add a testbench.
The decimation_strober now only starts counting when the valid flag is high.
It was necessary to adapt the input signal generation script so that the
Python model would remain consistent with the VHDL core.
