Summary: Let their types be determined by the atomic parameter only so that conversions may happen at the call-site. This is what the `std::atomic_compare_exchange` functions do. Those functions are specified to use `typename std::atomic<T>::value_type` rather than `T` but, curiously, not all implementations of `std::atomic` have member type alias `value_type`. So instead of using member type alias `value_type` to get dependency, we use `type_t`.

Summary: We currently call closeReceiver() on a receiver in receiversBySubscriptionId_ that has already been removed from receivers_ (and freed). The fix is to check to see whether the receiver in receiversBySubscriptionId_ is still present in receivers_ before invoking any functions on it. If the receiver is not present in receivers_, that means it has already been closed, so we do not need to close it.

Summary: Currently, when we get a cancelled notification on the output sender for a transform, we schedule the cancellation of any running transform callback on an executor. CancellationSource is thread-safe, so we don't need to do this. This diff ensures that cancelling the output receiver will immediately trigger cancellation of any running transform callback, allowing the transform callback to deterministically know that it has been cancelled.

Summary:
Move size and upper bound accounting to `UpperBitsReader`, so we don't need to read the last value on construction, which can be expensive when opening a large number of small lists.

This also makes the maximum `ValueType` representable, and lifts the requirement that the provided upper bound at construction time must be equal to the last element in the list, allowing multiple lists to share the encoding of the upper bound.

Based on initial work by swaroopnm.

Summary:
Add tests where the list size is close or at the maximum supported size, by fixing `EliasFanoReader` to support `uint16_t` as value and size type.

Types smaller than `int` require special support because any arithmetic operation promotes them to `int`, so operations that rely on unsigned overflow break. Work around this by introducing a helper for addition that preserves the type.
