Add JSON output format as non-default output option via new --format parameter

[scrthq]

Issue #, if available: #50

Description of changes:

• Adds --format parameter to ash/ash-multi scripts to enable additional output integrations, beginning with ASHARP (Automated Security Helper Aggregated Report Parser) as the intermediary data model to enable subsequent conversion from there.
• Adds automated_security_helper Python code as a module of the same name from within new src directory, including poetry.lock and pyproject.toml files to support. This module includes the asharp script (CLI tool) that enabled programmatic parsing of the aggregated_results content in conjunction with the JSON output changes.
• Adds pre-stage build of automated_security_helper module to Dockerfile
• Adds support to handle when --format is a value other than the current default of text so scanners switch output to programmatically parseable output formats and asharp is called to parse the aggregated_results.txt file into aggregated_results.txt.json.
• Moved source of version string truth into pyproject.toml for all projects, removed __version__ file to coincide with this.

I didn't do a deep review of asharp.py. Cursory look - it looks OK.

Minor comments in other places.

The updates look good to me - let's get this into main.
