Utilities for [DeviceCheck API](https://developer.apple.com/documentation/devicecheck).

DeviceCheck allows you to validate device tokens and query/update device state
bits to detect fraudulent activity on iOS, tvOS, and macOS devices.

# `build_auth_token!`

```elixir
@spec build_auth_token!(
  Apple.Types.DeviceCheck.issuer_id(),
  Apple.Types.DeviceCheck.key_id(),
  Apple.Types.DeviceCheck.private_key()
) :: String.t()
```

Builds a token to authorize DeviceCheck HTTP requests.

After building it, use it in the `Authorization` header like this:

```text
Authorization: Bearer <JWT>
```
