/// Generate a WASM client wrapper that gets exported in your WASM binary
/// This is required because WASM doesn't support generics and the regular
/// Client uses a lot of them. It will hard-code your exchanges, as well
/// as other options you may pass to the macro.
///
/// Additional options can be passed from JavaScript, only exchanges and the query enum are required.
/// The query enum is generated by [artemis-build](../artemis-build/index.html) and is located in
/// the root of your query module.
///
/// Make sure this is located in a WASM-only module or annotate
/// it with `#[cfg(target_arch = "wasm32")]`
///
/// # Usage
///
/// ```ignore
/// use artemis::wasm_client;
/// use artemis::default_exchanges::{DedupExchange, CacheExchange, FetchExchange};
/// use artemis_test::queries::wasm::Queries;
///
/// wasm_client! {
///     exchanges: [
///         DedupExchange,
///         CacheExchange,
///         FetchExchange
///     ],
///     url: "my_url",
///     queries: Queries
/// }
