TypeId $typeId not allowed. Why?

**Question**
Im trying to solve data migrations problem. Instead old model with typeId: 1, im creating new model with type: 2.
So im going to use numbers of higher order. Why there is a limit??

**Code sample**
```
if (typeId < 0 || typeId > 223) {
throw HiveError('TypeId $typeId not allowed.');
}
typeId = typeId + reservedTypeIds;

```

**Version**
- Platform: iOS
- Flutter version: 3.1.0-0.0.pre.1116
- Hive version: 2.1.0

Start by tracing the TypeId validation shown in the issue and reviewing Hive 2.1.0's type registration and migration documentation. Determine why the allowed range exists and whether the supported migration path is documented; done means the limitation and migration guidance are clear to users.
