[RNA] Use new tool to align RNA again RNA reference

Currenlty, sequenced RNA reads are mapped to transcriptome reference file using BWA. This tool requires a lot of computer resources.
Another tool : SALMON is very fast and low ressources comsuming pseudo-mapper for transcriptomic data.

Steps to add in the pipeline :

• Control and created if is needed index of transcriptomic reference
• Run SALMON
• Extract mapping rate from the log file -> will be done for NGL-Bi soon
