Simplified Adult Echocardiographic Report

Adds support for a simplified SR template for Adult Echocardiography Measurements.

It provides similar content to that of TID 5200 "Echocardiography Procedure Report" while addressing details that were the source of interoperability issues.

In particular it provides, with varying degrees and patterns of pre- and post-coordination, multiple codes for the same concept and numerous optional descriptive modifiers.
