Allow setting of all options in streamlined Plot.new function

[mindok]

The range of options that can be passed in Plot.new/5 is much more limited than what could be set creating the PlotContent manually. Extent to include at least more common options such as colour scheme.

As I recall you can pass any PlotContent option to Plot.new/5. E.g.,

Plot.new(dataset, BarChart, 300, 200, colour_palette: :pastel1)

[mindok]

Unfortunately it looks like they get ignored. I have a note in the roadmap to rationalise the option handling. If all the options are held as a keyword list rather than individual values in the struct, this streamlined API approach should be more reliable.
