DescriptorScanner 9.0.0-alpha.6 API

All Implemented Interfaces:

de.griefed.serverpackcreator.api.modscanning.ModJarScanner
```
public abstract class DescriptorScanner
 implements ModJarScanner
                    
```
Base for scanners that read one descriptor file out of each jar, owning the part every one of them shares: walk the jars, and turn any failure on a single jar into that jar's default ScannedMod instead of letting it abort the scan.
Subclasses implement read for one jar and may simply throw — which is why scan is final. The total-result contract of ModJarScanner is the one thing no scanner may get wrong, and putting it here means it cannot drift between the five implementations that used to each hold a copy.

 abstract ScannedMod read(File modJar)
```
    Read a single jar's descriptor into the verdict for that mod.
    Implementations are free to throw: scan catches everything and falls back to the defaults, so there is no need to guard the jar-level failure modes here. It is public because the distinction between what it throws is meaningful — MissingDescriptorException means the jar simply belongs to another loader, anything else means the jar could not be read — and that distinction is only observable here; scan deliberately flattens both to a default entry.
  - scan
```
 final List<ScannedMod> scan(Collection<File> jarFiles)
```
    Read every jar in jarFiles and report what each declared.
    
    Returns:
    
    One entry per input jar, in input order — never fewer, whatever a jar contained.
