Switch ADC and TAC in StripHit to unsigned int from double

[zoglauer]

Since this touches a bunch of classes, we need to have unit tests in place for these classes before the switch:

• MModuleLoaderMeasurementsHDF
• MModuleLoaderMeasurementsROA
• MModuleLoaderMeasurementsL0
• MModuleSaverMeasurementsL0
• MModuleLoaderMeasurementsFITS
• MFITSWriterL1a
• MModuleEnergyCalibration
• MDEEStripHit
• MCrystalHit
• MShieldCrystalHit
• MGuardringHit
• MDEECrystalHit

I would argue we don't need unit tests for

• MDetectorEffectsEngineSingleDet
• MDetectorEffectsEngineSMEX

if we plan to discontinue them (#175)

[zoglauer]

Fixed.

MShieldCrystalHit also seems like a left-over.
