Import of type used in inlined generic type generated

[jiftoo]

Hi. I noticed a bug or a limitation of this library. Consider this example:

use std::collections::HashMap;
use ts_rs::TS;

#[derive(TS)]
#[ts(export)]
pub struct Foo {
	#[ts(inline)]
	map: HashMap<usize, Bar>,
}

#[derive(TS)]
struct Bar {
	#[ts(inline)]
	map: HashMap<usize, Baz>,
}

#[derive(TS)]
struct Baz {
	#[ts(inline)]
	map: HashMap<usize, String>,
}

The .ts file produced by this snippet contains an import type statement referring to the first flattened generic type (Bar in this case), which is not used anywhere. No other imports are generated. Tested with Vec and HashMap.

import type { Bar } from "./Bar";

export interface Foo { map: Record<number, { map: Record<number, { map: Record<number, string>, }>, }>, }

The expected output should not include the first line. Please correct me if I'm missing something from the docs.
