Consider Amazon Ion Support

[atla5]

• add type protection to dates, ints, and other relevant fields as per fitting the standard
• add flag or warning and print statement for those items that cannot meet the strongly-typed standards given what it's gotten from the parsed input
• add Amazon Ion per-item and combined support triggered by -a and -A tags. (i might be taken by 'interactive' somewhere down the line)
• validate that this meets the Amazon Ion standards
