bugfix to BigWig backend using query.scale in getFeatures
make Wiggle tracks provide the current view scale in the query when fetching region stats.  results in huge performance gain for large bigwig files displayed with autoscale: local.

make sure we don't have fractional `start` or `end` in WiggleBase
