This function reduces the

  ep.physio,
  downsample_factor = 1,
  digital_channels = c("ttl_code", "ttl_onset", "Digital.*"),
  method = "subsample"
)

`ep.physio`	An ep.physio object created by read_acq
`downsample_factor`	An integer factor used to subsample data
`digital_channels`	Column names or positions containing digital channels, These will be downsampled using the `downsample_digital_timeseries` function to use the within-chunk mode, rather than blind subsampling.
`method`	How to downsample the signal. The default is `"subsample"`, which simply takes every nth sample from the original time series. The alternative is `"decimate"`, which calls `signal::decimate`. This applies a low-pass filter before downsampling to avoid aliasing. At the moment, there are big ringing artifacts at the beginning...
