Add twig function to print formatted output

Problem/Motivation

When printing dates with Twig, it would be helpful to be able to format the output, like you can with core dates, i.e.

{{ node.field_some_field.value|date('U')|format_date('some_format') }}

For reference, this functionality exists in the dev branch of the Smart Date contrib, as described here → .
