Reinit is broken while readme says it works

[Ten0]

Readme says "deinitialization does make it safe to reuse":

wkhtmltopdf-rs/README.md

Line 17 in c944f27

1. Wkhtmltopdf initialization can only occur once per process; deinitialization does make it safe to reuse

But the following test panics on second initialization, while the first one is dropped.

#[test]
fn double_init() {
	PdfApplication::new().expect("Failed to init PDF application");
	PdfApplication::new().expect("Failed to init PDF application");
}

Fwiw: I am no longer using or maintaining this crate (nor am I aware of the upstream maintenance or compatibility status of upstream wkhtmltopdf). I'd still do the bare minimum to merge a reasonable PR and/or republish the crate, and I'd entertain transferring the crate if there was a demonstrated effort to maintain it, but otherwise, I don't intend to invest in resolving issues like this one.
