v1.1.2

Changelog

• tx_is_valid and tx_outs_are_valid have changed from a bool return type to a (bool, String) return type, where the String contains reasoning or additional information about the nature of the validation.

Some Notes: In most cases, a correct validation will return no additional information at the chain level. For incorrect validations, the reasoning should in most cases provide more comprehensive context but may need to be updated when newer error types become possible
