Attribute Macro bind

#[bind]

Macro for generating byond binds Usage:

use byondapi::prelude::*;
#[byondapi::bind]
fn example() {Ok(ByondValue::null())}

#[byondapi::bind("/datum/example/proc/other_example")]
fn example_other(_: ByondValue, _: ByondValue) {Ok(ByondValue::null())}

Then generate the bindings.dm file with

#[test]
fn generate_binds() {
    byondapi::byondapi_macros::generate_bindings(env!("CARGO_CRATE_NAME"));
}

and run cargo test to actually create the file
