Feature: Add Mediation Networks

[ddxv]

Currently Mediation & Ad Networks are lumped together. They should be separated or designated so that information about them can be compared.

Example:

com.applovin -> AppLovin MAX 
com.applovin.mediation.adapter -> AppLovin MAX

com.applovin.mediation.adapter.unity -> Unity Adapter in AppLovin MAX
com.applovin.mediation.adapter.google -> AdMob Adapter in AppLovin MAX

Then this could be displayed like:

Top MAX Network Integrations:

Unity -> XX App Count
Google -> XX App Count

Finally, a place to compare mediation partners seems popular.

1. This could be done by either adding a new category and moving each company there.
2. Adding a new "SDK" for each Mediation partner, would require breaking apart metrics by SDK rather than company
3. Adding a tag for ad networks whether they have Mediation, adding filter on front end. This probably doesn't work for smaller mediation networks that have larger ad networks as it would incorrectly count regular SDK usage as that network's mediation usage.
4. Adding a "company" for each mediation platform + adding a new category. Probably the easiest, but might lead to logical confusion of what's the difference on the backend between a product vs company vs sdk
