Packs/unpacks arrays described by an explicit configuration object.

## Schema shape

```ts
{
  type: "array",
  maxLength: number,
  elementType: "integer" | "float" | "string" | "boolean" | "schema",
  elementMax?: number,        // for integer / float / string
  elementSchema?: BitPackerSchema // for elementType "schema"
}
```

## Behaviour

- Writes the array length using the minimum bits required for `maxLength`.
- Each element is packed according to its `elementType`.
- `float` elements are encoded as unsigned integers up to `elementMax`.
- `string` elements are encoded as fixed-length byte sequences (padded with null bytes).
- `schema` elements are recursively packed via the strategy chain.
