move denylist check from loader to the runner verification list

[andymck]

Linked proto pr: helium/proto#362

Moves the denylist check from the loader ( where invalids are dropped ) and into the runner's POC verification list. The denylist becomes a regular verification alongside the existing POC verifications and results in failed reports getting outputted to S3.

If a beacon is verified valid then the verifications are executed for each individual witness which and now includes the denylist check. The iot_poc file outputted to s3 will include metadata enrichment ( location, elevation & gain) for the beacon report and all witnesses (including for both valid and invalid witnesses) and will now include "DENIED" value for the invalid_reason where applicable.

If a beacon is verified invalid, all witnesses for that beacon are automatically rendered invalid without any verification checks being run on the witnesses. These invalid beacons will be in the iot_invalid_beacon files on S3, whilst the invalid beacons will be in the iot_invalid_witness files on s3. The beacon's invalid reason will be set to DENIED, as will be that of the witnesses. The witnesses participant_side field will be set to beacon to indicate they inherit the fail reason from the parent beacon.
In this scenario the beacon will now have the inclusion of the metadata enrichment fields but the witnesses will not ( as they are failed automatically without any verification checks and never get as far as checking for gateway info )
