Implemented logic to check if the system supports required services.
Logical edges with 'requires' fields are mapped only if physical edges
provide corresponding services. If not, the test is skipped.
This ensures that tests only run when the required services are available
in the test system configuration.
Fixes#654
SVG is a plain text file, better to see why it changed
than binary PNG. Also fix#744 by adding infix/OEM hash
to test specification
