Add `rastair`

Hello,

Please add rastair to the pipeline as an alternative tool to analyse methylseq data without bisulfite conversion (TAPS = TET Assisted Pyridine borane Sequencing).

Hi there,

rastair is already added to nf-core/modules as a subworkflow (called taps_conversion) including 4 different rastair modules. I am waiting on the final merge of the methylseq to be able to use it as a whole standalone pipeline in methylseq, which should come in the next couple weeks.
