use std::array to implement fixed arrays

`std::array` is byte-equivalent to a C style array, so this will always work with DF's structures, but using `std::array` gives us a lot of coding convenience on our side as `std::array` has much more reasonable semantics than a C-style array

these changes require a coordinated change in the dfhack repository
