[release] 1.18.1 - Return map copy of statsigUser with getClientInitializeResponse (#282)

Improvement:
-Instead of returning StatsigUser data class with
getClientInitializationResponse, return map copy of statsigUser so it is
more safe to serialize
- Context, jackson library cannot properly serialize StatsigUser
