      public static DefaultUsage fromJson(Integer promptTokens, Integer completionTokens, Long generationTokens, Integer totalTokens, Object nativeUsage)
      Create a new DefaultUsage with promptTokens, completionTokens, and totalTokens. This constructor is used for JSON deserialization and handles both the new format with completionTokens and the legacy format with generationTokens.
      Parameters:
      promptTokens - the number of tokens in the prompt
      completionTokens - the number of tokens in the completion (new format)
      generationTokens - the number of tokens in the generation (legacy format)
