Refactor error handling for memory allocation failure

**Describe the refactoring action**
The codebase uses C++'s `new` but handles allocation failures as if it were C's `malloc` by checking if the returned pointer is NULL, while `new` in C++ throws a [std::bad_alloc](https://en.cppreference.com/w/cpp/memory/new/bad_alloc) if it fails, unless the call is marked with [std::no_throw](https://en.cppreference.com/w/cpp/memory/new/nothrow).

**Possible actions**
* Do nothing: If we leave the NULL checking code as is then it just stays as dead code. This is not a particularly high-severity issue IMO
* Add `std::no_throw` to the calls to `new`. This will keep the current error handling code as new will return NULL on failure.
* Remove the error handling code: Allocation failure means something else has gone terribly wrong and there is little that can be done to handle a bad_alloc [[1]](https://stackoverflow.com/questions/1308052/policy-with-catching-stdbad-alloc) [[2]](https://stackoverflow.com/questions/9456728/how-to-deal-with-bad-alloc-in-c), so might as well let it go uncaught and terminate the program. We can replace some of the calls to new with smart pointers where the API permits.
