Trial results are only saved to AWS when <= 25 trials #55

I noticed that trial results for longer experiments didn't get saved to DynamoDB, and learned that BatchWriteItem is limited to 25 items at a time. Data for experiments with <= 25 trials is saved fine, but for >25 the BatchWriteItem call fails and nothing is stored to the TrialResults table (just confirmed this with 2.1.0 on Unity 2019.4.16f1 LTS).

My quick and dirty solution was to submit the data in batches of 25, which has been working fine in a running experiment so far. Let me know if a PR would be helpful!

Thanks! I am shocked I didn't encounter this during testing. I will take a look.
