Patches the metadata structure for the Colorado Boulder tracked SSA HDF5 files.

Changed files: 62 total.

Folders changed:

• colorado-boulder/Sub-dataset-1/: 10 files
• colorado-boulder/Sub-dataset-2/: 10 files
• colorado-boulder/Sub-dataset-3/: 42 files

Fields changed:

• subject information is now stored under metadata/subject/id
• subject information is now stored under metadata/subject/type
• us_machine is now stored as a file-level attribute

Incorrect previous fields removed:

• metadata/subject_id
• metadata/subject_type
• metadata/us_machine

Reason:
The previous patch placed subject_id, subject_type, and us_machine directly under /metadata.

This patch moves the subject fields to the ZEA-compatible metadata/subject/ group and stores us_machine as a file-level attribute.

Subject values:

• Sub-dataset-1: metadata/subject/type = "2d_phantom"; metadata/subject/id follows the phantom2d file ID
• Sub-dataset-2: metadata/subject/type = "3d_phantom"; metadata/subject/id follows the phantom3d file ID
• Sub-dataset-3: metadata/subject/type = "invivo"; metadata/subject/id follows the invivo file ID

us_machine value:
"Verasonics Vantage research ultrasound scanner with a 64-element Verasonics P4-2 phased-array transducer"

Raw RF data and acquisition data are untouched.
