lf/data combined detectclock functions to one

cleaned up detect clock functions - now uses one main function that
takes a char argument to select which modulation to detect the clock for
REMOVED commands: pskdetectclock, nrzdetectclock, fskfcdetect.
renamed DetectClock function to DetectAskClock to be more descriptive.
