/**
|
|
* Trait containing I/O methods for handling legacy Anvil-style chunks.
|
|
*
|
|
* Motivation: In the future PMAnvil will become a legacy read-only format, but Anvil will continue to exist for the sake
|
|
* of handling worlds in the PC 1.13 format. Thus, we don't want PMAnvil getting accidentally influenced by changes
|
|
* happening to the underlying Anvil, because it only uses the legacy part.
|
|
*
|
|
* TODO: When the formats are deprecated, the write parts of this trait can be eliminated.
|
|
*
