Add AdqReduce reduction plugin

Reduction plugin specific to ADQ digitizers to exploit various data reduction opportunities commonly encountered in the field.

• Remove output modes entirely
• Remove channels empty due to interleaving
  • Commonly encountered pre-2025/1 as the AdqDigitizer device had a bug not removing these channels from its schema
  • Detected automatically either from RUN data or all-zero raw data
• Remove channels with no actual signal connected to it
  • Compares the RSME across discrete windows with the median to distinguish signal from no signal
