Generate data suitable for creating a court overlay plot

1	os_overlay_data(court = "tennis", space = "court", court_ref, crop = TRUE)

`court`	string: court to plot, currently only "tennis"
`space`	string: if "court", the data will be in court coordinates. If "image", the data will be transformed to image coordinates via `ovideo::ov_transform_points()`
`court_ref`	data.frame: as returned by `os_shiny_court_ref()`. Only required if `space` is "image"
`crop`	logical: if `space` is "image", and `crop` is TRUE, the data will be cropped to the c(0, 1, 0, 1) bounding box (i.e. the limits of the image, in normalized coordinates). Requires that the `sf` package be installed
