v1.3.31

• updating GL-est-rRNA-percentages
  • added --directRNAseq flag for when input reads are RNA sequences with Us instead of Ts
    • this makes temp read files with U's converted to T's prior to passing to hts_SeqScreener, as that won't allow U's (temp files are made instead of streaming from a pipe because I couldn't figure out how to get hts_SeqScreener to take the start from standard in even for 1 input, letalone if there were paired-ends)
