Rubbish values from Node.source after editing tree

[xcb-xwii]

After editing a certain range of the tree using Tree.edit / Tree.edit_s, some calls to Node.source will return rubbish values.

This seems to only apply to nodes that were not affected by the edit. Nodes that did experience changes will return their source text correctly, while unaffected nodes return what I can only assume is junk.

Read through the code and found this line:
https://github.com/euclidianAce/ltreesitter/blob/0c63020d861b6a3cfa5ff9a756a512b3efc533a3/include/ltreesitter/types.h#L31C1-L31C1

The lack of support for a reader function might be the cause instead. The testing during which I encountered this uses a reader function.
