Configure whether or not the resulting IO configuration will accept legacy-formatted data.

<p>The legacy format was used in versions of Minecraft prior to 1.13</p>

<p>Be aware that because the legacy int array and modern list are ambiguous with each other,
the deserializer will always return legacy-format integer arrays as a list tag.</p>
