Generics don't work with `inline` and `flatten` when they have a default type or a trait bound

Generics don't work with `inline` and `flatten` when they have a default type or a trait bound

I'd love to find a solution to this. I think I get what's happening, but i'll have to really go through it all in detail to understand all the edge cases.
That being said, I feel like the workaround is alright for most usecases - IMHO, trait bounds on structs are barely ever neccessary (though people seem to often put them there). I had to google a bit to find good examples for when it's actually required (except Send, Sync or ?Sized).

@NyxCode I managed to get this working!
The user will have to do the following:

#[derive(TS)]
struct Unit;
impl ToString for Unit {
    fn to_string(&self) -> String {
        "".to_owned()
    }
}

#[derive(TS)]
#[ts(unit_type = "Unit")]
struct Generic<T: ToString> {
    foo: T
}
