Elevation property for add_text()

[Zekiye-VAP]

What do you want the feature to do?
Wondering if it is possible to change the elevation of text added to a map using add_text(). When combined with other layers that do have elevation, the text becomes very hard to read. See image for example of text (A, B, C, D characters) being obscured by elevated polygons.

Would be great to have a dynamic elevation so the text can sit above other elevated layers.

This currently works if your 'text' data is an sf object with a Z attribute:

library(mapdeck)
library(sf)
library(sfheaders)

set_token(secret::get_secret("MAPBOX"))

df <- data.frame(x = 0:5, y = 0:0, z = c(100000, 0, 100000, 0, 100000, 0), label = letters[1:6])

sf <- sfheaders::sf_point(
	obj = df
	, x = "x"
	, y = "y"
	, z = "z"
	, keep = TRUE
)

mapdeck() %>%
	add_text(
		data = sf
		, text = "label"
	)

it needs a bit of work to get the data.frame version working.
