palimpsest_DissectSigs for null clonal or subclonal

[jh2663]

Hi, I just find that palimpsest_DissectSigs() has no option to tag out some samples with null (zero entries) clonal or subclonal groups in the input dataset.

It returns following error possibly because it can't compare null group vs other one:

Error in plot.window(xlim, ylim, log = log, ...) :
need finite 'ylim' values

Best,

p.s1. I was able to handle this issue by manually removing such a sample from input 'vcf' data frame but it would be good to consider this in the next update.

p.s2. The same issue happens with palimpsest_plotTumorHistories() function. It can't make a proper plot for samples with no subclonal entries.
