`type_text(labels = <lab>)` should work without characters

[grantmcdermott]

MWE: This simple example fails because Species is a factor variable:

library(tinyplot)

with(iris, plt(Sepal.Length, Petal.Length, type = type_text(labels = Species)))
#> Error: `labels` must be character.

Cause: The assert_character() line here is too strong.

tinyplot/R/type_text.R

Line 31 in c31c26b

assert_character(labels, name = "labels")

Do we need an assertion here at all? What's wrong with passing numeric to labels, for example?

You're right. Everything that is supported by the text() function should be fine for us.
