Implementation of HIP-131 (#858)
Browse files Browse the repository at this point in the history 
* Save ban_type to db when receiving new ban reports

* Update query

* Update coverage_point_calculator to accept hip131_ban boolean

* Update mobile-verifier to pass pan flag to coverage point calculator

* Update cargo lock

* Update new test

* Change bool to OracleBoostingStatus enum

* Address feedback, move oracle_boosting_status into RadioInfo

* Update Cargo.lock

* use radio_info as the source for all that we can

Why pass in information from a source that we're going to be using
gratuitously within the same function. Did I spell that right?

* Update proto back to master

* Update helium-proto to tip of master
