Optimize read length input for QoRTs (Folsomia project)

[mattjmeier]

Regarding the RNAseq pipeline for Folsomia candida...

Ion Torrent data tends to be variable in length. It would be useful to determine the length of the longest read in a dataset, and set that as the limit in QoRTs - otherwise it will throw an error and crash (if longest read exceeds hard limit), or graphs will look terrible because they are set to an absurd length.
