This adds support for a `float_hook` to the json decoder. If set, this hook will be called to decode any untyped JSON float values from their raw string representations. This may be used to change the default float parsing from returning ``float`` values to return ``decimal.Decimal`` values again. Since this is an uncommon option, it's only available on the Decoder, rather than the top-level ``msgspec.json.decode`` function.
