Smarter default values for params like `text_size` and `text_thickness`

[HaleySchuhl]

Is your feature request related to a problem? Please describe. It's verbose to adjust some parameters like pcv.params.text_size and pcv.params.text_thickness so make different plots interpretable by a user (e.g. text_size needs to be much larger for pcv.visualze.colorspaces than pcv.visualize.object_sizes). There is probably programmatic ways that we could auto-adjust these values to avoid adding those lines into a workflow that is being developed multiple times.

Describe the solution you'd like Maybe multiplier based on the function? Include scaling based on image size?
