Expand description

This type enables wrapping a tuple to preserve the behavior of the initial implementation of tuple key encoding. This type should not be used in new code and should only be used to preserve backwards compatibility. See https://github.com/khonsulabs/bonsaidb/issues/240 for more information about why this implementation should be avoided.
