added Ignore errors option to keep processing records

[trunksio]

Firstly - I think this is a great utility. My use case is I have a large number of json files in s3, however a number of them cross the 1mb threshold. I want to be able to process as many as I can, but be aware of those files which cannot be processed by s3 select. The added -I option will not retry but will output the exception and keep going.
