Do you think it would be easy to do a c2nim wrapping (similar to bindgen) and expose libpostal to Nim?

Hi, I'm trying to use this in a async_graphql context, however I can't use expand_address at all because it expects all structs to implement Send:

future cannot be sent between threads safely
within `impl std::future::Future`, the trait `std::marker::Send` is not implemented for `*mut *mut i8`

I was able to share the postal context using an Arc<Mutex<>>, but it's not possibleto do the same for the options. Could you have a look at it?

When using the expand_address binding I am unable to pass more than one language code to the ExpandAddressOptions. I can pass a slice with only one language in it, but as soon as I pass a second value I get a segfault.

See example code here, which yields the following results:

Testing:
Address: "Foo Str"
Language(s): ["en"]
Results: ["foo street", "foo strata unit"]
Testing:
Address: "Foo Str"
Language(s): ["de"]
Results: ["foo strasse"]
Testing:
Address: "Foo Str"
Language(s): ["de", "en"]
[1]    20143 segmentation fault  cargo run

Expected result (using PyPostal):

In [1]: from postal.expand import expand_address

In [2]: expand_address("Foo Str", languages=["en"])
Out[2]: ['foo street', 'foo strata unit']

In [3]: expand_address("Foo Str", languages=["de"])
Out[3]: ['foo strasse']

In [4]: expand_address("Foo Str", languages=["de", "en"])
Out[4]: ['foo strasse', 'foo street', 'foo strata unit']
