--no_resample + .raw = pipe error

[bradriley]

Signed 16-bit input with DdD's default .raw extension immediately returns a pipe error if paired with --no_resample.

Not sure if directly related:
Despite being 40 -> 40 MSPS, --no_resample consistently runs a little faster than default options.

Example trimmed .raw file: casper2pana1F.raw.zip

brad@mini ddd % vhs-decode --no_resample casper2pana1F.raw error

Two workarounds:

1. Don't use no_resample.

brad@mini ddd % vhs-decode casper2pana1F.raw workaround1
Phase previously set: 0
phase0 mean: 5661.34
phase1 mean: 374.79

saving JSON and exiting #None Unknown

2. Rename to .s16.

brad@mini ddd % mv casper2pana1F.raw casper2pana1F.s16
brad@mini ddd % vhs-decode --no_resample casper2pana1F.s16 workaround2
Phase previously set: 0

saving JSON and exiting #None Unknown     

(Note: every run above actually included a Numba Deprecation warning, which I deleted from the paste and filed separately as issue #100.)
