More hodoscope cleanup. Replace arras with THcHodoHit clones array

   Don't repeat comparisons of tdc values
   with fScinTdcMin and fScinTdcMax because hits only get added to
   fHodoHits (and previously fPosTDCHits, fNegTDCHits, ...) if
   the times are within these ranges.
  In THcHodoscop, remove members of fTOFPInfo that are just used
   locally.
