Papy60

• Now FACETS can be used on OncoScan, OncoScan_CNV, CytoScan750k and CytoScanHD arrays (still not on SNP6, though).
• Some bugs corrected, too.
• Sequenza CN output fixed.
• Changed the formula for the "most width" ploidy version, so that a value of 0 can't be returned.
• Paving the way to handle non-canonical genomes in the report (not active yet, though).
• Small code changes to adapt to "non-completely covered" genomes (ie, few chromosomes for toy datasets, by example).
• Harmonized the penalty parameter for all segmenters (now just "penalty" rather than "ASCAT.pen", "SEQUENZA.pen" or "FACETS.pen")
• Officially dropping support for sequenza with SNP6 arrays as it leads to a huge RAM consumption by copynumber::aspcf, due to the few probes covering both L2R and BAF.
• Included chromosomes objects in package for hs, mm and rn, to avaoid dependency to another non-public sourceable package.
