Add consensus approach

[tiagofilipe12]

Given that this pipeline accepts many approaches ranging from mapping, assembly and mash screen, a useful output would be to make a consensus between all the approaches and report it to the user in a JSON format to import in pATLAS.

This could be implemented by just adding the result to each accession entry to a report JSON file. E.g.

{"a_given_accession": 
  {
    mapping: 0.91, 
    mash_screen: 0.93, 
    mash_dist: 0.7
  },
"another_accession": 
  {
    mapping: 0.6,
    mash_screen: 0.9,
    mash_dist: 0.8
  }
}

Then this JSON file would be read by pATLAS. For further information on how to implement this in pATLAS go to tiagofilipe12/pATLAS#124.
