Make hubApi wig table output behave like a bedgraph instead of having a top level key with the chromosome name that contains all the data, now there is a key with the trackName and then bedgraph like data of chrom,start,stop,value. Does not affect bigBed output which already worked this way. Clean up some missing 'let' declarations and fix some for loop logic in the download data in window feature, refs #36802,#36858
