Replace Gson and org.json with kotlinx.serialization

Why/Project’s Benefit/Existing Problem

There are in the repo actually:

• 1 file that uses Gson;
• 4 files that uses JsonParser from Gson;
• 14 files that uses Kotson; and
• 7 files that uses org.json

All the usages of other Json libraries for deserialization should be replaced by kotlinx.serialization.

Other details

The Json singleton instance with ignoreUnknownKeys = true from the main app can be reused:

private val json: Json by injectLazy()

It is not needed to add the kotlinx.serialization dependency to the extensions that uses it (with Json or ProtoBuf), since it was already added to common-dependencies.gradle. However, extensions that make usage of the library must add this one line after the kotlin-android plugin at the extension’s Gradle file:

apply plugin: 'kotlinx-serialization'

Closing this since replacing org.json isn’t really necessary, although it is a nice-to-have.
