issues-209: Add missing imports for GCC 12/13

Resolves #209 (closed)

• To make the project compile with GCC 12 or newer: #include <array> (https://gcc.gnu.org/gcc-12/porting_to.html)
• To make the project compile with GCC 13 or newer: #include <cstdint> (https://gcc.gnu.org/gcc-13/porting_to.html)

(This is the second version of this merge request, the previous one included an outdated author email in one commit and could not be merged due to missing ECA info.)
