ModeAHDC thread safety

[baltzell]

The extract method is no longer thread safe, particularly these member data:

coatjava/common-tools/clas-detector/src/main/java/org/jlab/detector/pulse/ModeAHDC.java

Lines 52 to 57 in 8b232c1

	private short[] samples;
	private Pulse pulse;
	private long time_ZS;
	private int binMax;
	private int numberOfBins;
	private int effectiveNumberOfBins;

For example, when sample count gets overwritten by a competing thread, from any RG-L logs:
