Transform all u8 arrays by default (#362)

* Transform all u8 arrays by default

The current behaviour confuses devs because some `u8` arrays are being turned into `BytesTypeNode` but not others based on their size. This PR fixes this by transforming all fixed-size arrays of `u8` numbers into a `FixedSizeTypeNode` of `BytesTypeNode`.
