* "mts" - a string containing the binary MTS data used in the MTS file format
* "lua" - a string containing Lua code representing the schematic in table format
* `options` is a table containing the following optional parameters:
* If `use_comments` is true and `format` is "lua", the Lua code generated will have (X, Z)
* If `lua_use_comments` is true and `format` is "lua", the Lua code generated will have (X, Z)
* position comments for every X row generated in the schematic data for easier reading.
* If `lua_num_indent_spaces` is a nonzero number and `format` is "lua", the Lua code generated
* will use that number of spaces as indentation instead of a tab character.
### Misc.
* `minetest.get_connected_players()`: returns list of `ObjectRefs`
