async/await React Native

Quando tento usar async/await diretamente, lança o erro:

```ts
Possible Unhandled Promise Rejection (id: 0):
TypeError: (0, _cepPromise.cep) is not a function. (In '(0, _cepPromise.cep)(86055645, {
providers: ['correios']
})', '(0, _cepPromise.cep)' is undefined)
```

Criando um async, funciona. Portanto, acredito que o cep-promise deveria ser rearranjado para funcionar com async/await diretamente.

```ts
async function CEP(CEP: string) {
return new Promise(resolve => {
cep(CEP, {timeout: 5000, providers: ['brasilapi']}).then(response => resolve(response));
});
}

const cepResponse = await CEP(userInfo.postal_code);
console.log('cepResponse ', cepResponse);
```

Start by reproducing the direct async/await call to the `cep` entry point in a React Native environment, then compare it with the wrapper function shown in the issue. Check how the package exports `cep`; done means direct async/await usage works without the reported TypeError and the behavior is covered by a regression test.
