Still need to implemente resampling in NF instead of just python

Prior, Digitizer took all untagged traces.  These two should be equivalent in
the context of simulation.

In the, until now nonexistent, case of reading a voltage frame from a FrameFileSink-produced file, the '*' bets (mis)interpreted to be a trace tag instead of being a wild card and this caused Digitizer to not get any traces.

The entire situation with frame and trace tags is a big jumbled and deserves to be straightened out globally.  But, for now, this makes things work and really tags have no place in simulation so should be correct going foward.

- Add artifact mitigation to Resampler via different time-domain padding strategies.

- Add a CLI Jsonnet to run just the Resampler.

- Move from a BATS test to a Snakemake file to run everything as it is starting to get complex.
