Add spa-type analysis to Nanopore track

[Emkago]

Add a module for spa typing to Nanopore track. Despite knowing that spa-typing is not the best method for tracking relatedness of strains, it is one of the parametres that needs to be reported to SmiNet when using long read sequencing and some would like to have it for historical reasons.

It is also available as nf-core module.
