+Subject: [PATCH] Add #include <cstdint> to compile with gcc13
+
+The `vtkSEPReader` was introduced by MRs !4909 (from my former
+collaborator Maxime) and !4938. Then it was highly modified by
+!7516. The later MR is the one that introduced the uses of
+`std::uint8_t` and `std::uint32_t`.
+
+Those types needs the inclusion of `<cstdint>`.
