v2.0.0

Major update including:

• Significantly simplified pipeline
• Streamlined polar_coords() function no longer requires a complex p-value table object
• Conduit functions to make it much easier to make 3d volcano plots and 3-way polar plots from gene expression analysis using 'DESeq2' and 'limma voom'
• Inbuilt statistical tests for group comparison (one-way ANOVA) and pairwise comparisons with easy calculation of p-values and optional adjustment for multiple testing
• polar_coords() is thus able to accept more general data
• Back compatibility has been maintained for old 'polar' class objects
• volcano_plot and volcano_trio functions have been deprecated and removed
• Bug fixes
