Allow lists of run numbers and run ranges in THcParmList::Load

[sawjlab]

When Load is called with a run number, then the input file is ignored until a line with a list of run numbers or run number ranges is found. For example: 44,50-90,113 If the run number matches one of these run numbers or ranges, parameter definitions after the match are loaded. (Until the next list of run numbers and ranges.) Before this commit, only a single run number or a single range of run numbers was allowed.

I found that this did update did not break things.
