Missing RTL support

[emilyyyylime]

The following example and pretty much every usage of the package renders completely broken:

#import "@preview/pinit:0.2.2": *

#set text(dir: rtl)

$ E #pin(1) = m c^2 $

#pinit-point-from(1)[hi]

Removing the set text(dir: rtl) of course gives the expected result
