Drop `Flume.feed`, it's unused yet causes import cycles..

Replace the debug breakpoint with a warning-log when a single-bar
null-segment is detected in `get_null_segs()`. This lets the gap
analysis continue while still alerting about the anomaly.

Deats,
- extract the 3-bar window (before, null, after) and calculate
  a `gap: pendulum.Interval` for the warning msg.
- comment-out the old breakpoint block for optional debugging as needed.
