Range plot for stratigraphic sections

[bethany-j-allen]

Is your feature request related to a problem? Please describe.
This problem was raised by Meghan Jenkinson (via X): an R-based way to plot stratigraphic range and occurrence data for an individual section.

Describe the solution you'd like
An extension of tax_range_time which plots ranges across beds within a section, including points indicating specific sampled levels, and ideally with open points for uncertain identifications.

Describe alternatives you've considered
These figures are common but typically made by hand for manuscripts, but it should be possible to generate them automatically from the input data.

Additional context
I already have some code from Alex Dunhill; I will be working on a full draft over the next couple of weeks.
