HIP-119 introduces a new set of tables for location trust scores based on `(radio_type, distance_to_asserted)`.

This also allows for a new minimum trust score multiplier of `0x`.

This value is now contained within the function `asserted_distance_to_trust_multiplier` in the coverage point calculator.

All location trust scores used to be 1.0 or 0.25. HIP-119 adds 0.00 as a multiplier possibility based on distance.

Location Trust Scores are no longer reduced based on the presence of a
boosted hex. However, having an average distance from an asserted
location past 50m can cause a radio to be ineligible for boosted rewards.

Both constants have to do with service provider boosting in regards to a
radios location trust scores. Namespacing allows for not needing to
shove all possible context into a top level name.

It didn't feel quite correct to have half the service provider boosting
code in lib.rs and the other in location.rs.

The constants have to with location trust scores, but they do not get
used there.

The distance to asserted no longer changes trust scores in the presence
of a boosted hex. Service provider boosting eligibility is determined
from the distance to asserted, that is tested at the top level of this crate.

The only difference was the location distance from asserted and assigned
location trust multipliers.

Refactoring heartbeat seeding further is left as an exercise to the next
person who has a need to change these tests.

…osting

HIP-119 removes the part of calculating coverage points that degrades a
trust score when a radio covers a boosted hex and is more than 50m away
from their asserted location.

Now, being +50m away from an asserted location makes a radio not
eligible for receiving service provider boosted rewards. They continue
to receive the full force of their location trust score.

Being an Indoor radio 100m away from an asserted location is enough to
keep a location trust multiplier of 1.0x, but not receive boosted rewards.

Adding links to multiple places so you don't have to know a secret
location where they exist.

Both were answered yes

CBRS is always trusted for location. The location trust score is intercepted earlier when validating heartbeats. If for some reason CBRS radios do make it to this function, they will receive a good trust score anyways.
