PutLogEvents request must be in chronological order

[giantcow]

In my use case, I'm combining my own logs from tracing, with logs from tracing-gstreamer. With the Gstreamer tracing logs enabled, I sometimes get the following error:

[tracing-cloudwatch] Unable to put logs to cloudwatch. Error: Other(InvalidParameterException: Log events in a single PutLogEvents request must be in chronological order.

Caused by:
    InvalidParameterException: Log events in a single PutLogEvents request must be in chronological order.

I think we could easily add a sort, but I'm very worried about the efficiency implications

Thank you for reporting the issue.
I plan to add support for sorting. Considering the impact on performance, I may make it configurable to control whether sorting is performed or not.
