Protobuf allow field number to be set to value non in specification

**Describe the bug**
E.g.: it allow to set a field number to 0.

**To Reproduce**
```kotlin
@Serializable
data class Box(@ProtoNumber(0) val number: Int)
```

**Expected behavior**
Shoud throw an error, this is not [spec](https://developers.google.com/protocol-buffers/docs/overview#assigning_field_numbers) compliant as it should only allow value between 1 and 2<sup>29</sup> - 1.
