Setting to false preserves library's behavior prior to 3.6, where companion object constructors were only considered when deserializing if there were no primary constructors. Setting to true preserves the backwards-incompatible change made in 3.6 to always consider companion object constructors when deserializing (https://github.com/json4s/json4s/pull/487).

Prior to 3.6 companion object constructors were only considered when deserializing if there were no primary constructors. A backwards-incompatible change was made in 3.6 to always consider companion object constructors when deserializing (https://github.com/json4s/json4s/pull/487), and is the default setting (considerCompanionConstructors = true). This changes the setting to false to preserve pre-3.6 deserialization behavior.
