Motivation and Context

We have most of what we need from ST 1303 (array encoding) for MIMD and ST 1206, but coverage isn't too good on other aspects, especially on 1D signed integer, and some other natural format encoding. I'm working down the list in preparation for future MIMD and some of the lesser-used formats which potentially need this.

Relates to #198, but doesn't complete it.

Description

Adds encoding for:

• 1D signed integer in natural format
• 2D unsigned integer in natural format
• 2D boolean in natural format

Adds decoding for:

• 1D signed integer in natural format

Fixes some minor issues and test naming in existing code.

How Has This Been Tested?

Re-ran unit tests as part of full build.
