[FEATURE] Create PICS-to-XML conversion script

[rquidute]

Summary

Add two utility scripts to convert PICS log data into XML PICS files compatible with the Matter certification tool's Generic-PICS-XML-Schema.xsd schema.

Scripts

scripts/pics_to_xml.sh (bash)

• Accepts two input formats:
  1. Python dict log format: PICSItem(number='KEY', enabled=True/False)
  2. Raw KEY=0/1 lines (or inside an echo '...' block)
• Produces one XML file per cluster prefix (e.g. MCORE.xml, JFADMIN.xml)
• Pure bash + awk + perl — no extra dependencies

Usage

# bash version
./scripts/pics_to_xml.sh <input_file> [output_dir]

# Python version
python scripts/pics_to_xml.py <input_file> [-o output_dir]
python scripts/pics_to_xml.py --text "MCORE.S=1\nMCORE.C=0" [-o output_dir]

XML output structure

Each output file follows the clusterPICS schema with sections:

• usage — top-level cluster usage items (e.g. ACL.S, ACL.C)
• clusterSide type="Server" / type="Client" — per-side attributes, events, commandsGenerated, commandsReceived, features, manually
• miscellaneous — items that don't fit the Server/Client structure

Motivation

When running certification tests, PICS data is available as TH log output or as KEY=0/1 shell blocks. These scripts automate the conversion into the XML format required by the certification tool, eliminating manual XML editing.
