fix: use sane value for json_tokener max_depth
INT_MAX causes a NULL pointer if there is not enough memory available to
fit (INT_MAX * sizeof(struct json_tokener_srec)).
#define _POSIX_C_SOURCE 200809L

+// arbitrary number, it's probably sufficient, higher number = more memory usage
+#define JSON_MAX_DEPTH 512
