Create image masks for NF1 test data

[d33bs]

Description

This PR adds image masks for NF1 test data using a cppipe CellProfiler file provided by @jenna-tomkinson and existing test data sampled from Plate 2. The focus here is solely on adding test data and tracking provenance through the pipefile and a Docker-based processing of the image files into masks.
