-### Map<String, Object> and Numbers
-The default constructors of `MoshiEncoder` and `MoshiDecoder` decoder numbers in
-`Map<String, Object>` as Integer type. This prevents reading `{"counter", "1"}`
-as `Map.of("counter", 1.0)`.
-
-To change this, please use constructors that accept a Moshi object.
