Filter for anomalous exit legs too

[Nate-Wessel]

What this pull request accomplishes:

• applies leg-specific anomalous_ranges to exit legs too (formerly only applied to entry leg)

Issue(s) this solves:

• resolves Miovision volumes_15min_* views do not properly filter leg-specific anomalies #1265

What, in particular, needs to reviewed:

• logical correctness
• that moving the conditions from a JOIN to the WHERE clause doesn't slow things down at scale (I tried it filtered down to the small example from the issue and it didn't take any longer)

What needs to be done by a sysadmin after this PR is merged

• replace the view

I do believe you raise a good point about exit volumes not being handled correctly, but I think it applies only to the volumes_15min_atr_filtered view.
