Package options `pgf` and `no-tikz` #2

Closed simon-pfahler closed 6 months ago

This adds the package options pgf and no-tikz to allow the user to decide which packages colorblind should load. Continuous colormaps are only available with the option pgf, and no-tikz disables the command \drawScheme.
