plot_cpdb4

[zktuong]

new function! plot_cpdb4 very similar to plot_cpdb3 but some stylistic choices applied.

minor plotting bug fixes for plot_cpdb3.

refactored the weird character pattern to hopefully now catch more patterns more reliably.

changed version3 to degs_analysis to keep it consistent with the main cellphonedb mode.

now in plot_cpdb3 and plot_cpdb4, it tries and correct the directionality of the ligand/receptor arrows so ligands should always point to receptors. if both are receptors, it will use the original cellphonedb ordering.
