Creates a new DTLS listener bound to the provided socket address using the specified configuration.

### Method
ASYNC FUNCTION

### Endpoint
webrtc_dtls::listener::listen

### Parameters
#### Arguments
- **laddr** (ToSocketAddrs) - Required - The local address to bind the listener to.
- **config** (Config) - Required - The DTLS configuration settings.

### Request Example
```rust
let laddr = "127.0.0.1:4444";
let config = Config::default();
let listener = listen(laddr, config).await?;
```

### Response
#### Success Response (Ok)
- **impl Listener** (Result) - Returns an implementation of the Listener trait upon success.

#### Error Response (Err)

### Blanket Implementations for Generic Types in Rust

Source: https://docs.rs/webrtc-dtls/0.12.0/webrtc_dtls/curve/enum.EllipticCurveType.html?search=Option%3CT%3E%2C+%28T+-%3E+U%29+-%3E+Option%3CU%3E

Showcases blanket implementations for generic types, demonstrating how traits like Any, AsTaggedExplicit, AsTaggedImplicit, Borrow, BorrowMut, CloneToUninit, From, Into, Same, ToOwned, TryFrom, TryInto, and VZip can be applied to various types.

```Rust
impl<T> Any for T
impl<'a, T, E> AsTaggedExplicit<'a, E> for T
impl<'a, T, E> AsTaggedImplicit<'a, E> for T
impl<T> Borrow<T> for T
impl<T> BorrowMut<T> for T
impl<T> CloneToUninit for T
impl<T> From<T> for T
impl<T, U> Into<U> for T
impl<T> Same for T
impl<T> ToOwned for T
impl<T, U> TryFrom<U> for T
impl<T, U> TryInto<U> for T
impl<V, T> VZip<V> for T
```
