update to kraken2: breaking change - output channels renamed (#1525)
* updated kraken2 module to include optional classification of each input reads, and make fastq outputs optional
NB: this is a breaking change, because the output channels have been renamed as a consequence of changes

* updated yml

* pigz command made optional, in order to be executed only if fastq of classified/unclassified reads are saved

* updated test yaml file for kraken2

* fixed TODOs and renamed variables and outputs

* untar in conda cannot keep same md5sum of version, and therefore md5sum check removed

* improved description of the options
