Unify enhanced_exi_viewer with Wireshark XML output and encoding support

Browse Source 
- Remove unused XML output modes (ISO1, ISO2), keep only Wireshark-style output
- Integrate encoding functionality from enhanced_exi_viewer_simple
- Single executable now supports both encoding and decoding:
  * -decode: Convert EXI to Wireshark-style XML with ns1-4 prefixes
  * -encode: Convert XML to EXI format
  * default: Detailed EXI analysis mode
- Support for both standard XML tags and namespaced (ns3:) tags in encoding
- String conversion for units (A, V, W, s) and error codes (NO_ERROR)
- Compact XML output matching Wireshark format exactly
- Clean up old test files and separate tools
