A wrapper class which provides array bounds checking.
We do not own the array, we simply have a pointer to the first element, and a length.
This is roughly analogous to C++20's std::span.
Element_type | The type of the elements of the container. |

typedef Element_type* Bounds_checked_array< Element_type >::iterator |

Does not resize the underlying array, so the new size must be smaller than or equal to the current size.
