Several combined improvements/fixes in the main pyftsat code

1) Fixes missing passing of binary argument ot the search tool
(previouslly, the binary parameters where not searched over!)
2) Adds min/maxfraction to cumulative plot and fixed start times
3) Adds binary parameters to cumulative plot call
