This fixes a long-standing issue where strings like '1e10' or '0755' were being output without quotes by 'aws cloudformation package', causing them to be misinterpreted as numbers when re-parsed. Added a custom string representer to yaml_dump that identifies and quotes ambiguous strings (scientific notation, octal, hex, binary, and sexagesimal formats).

This PR fixes issue #3991 where strings like '1e10' or '0755' were being output without quotes by 'aws cloudformation package', causing them to be misinterpreted as numbers when re-parsed.
I've added a custom string representer to yaml_dump in yamlhelper.py that identifies and quotes ambiguous strings (scientific notation, octal, hex, binary, and sexagesimal formats).
