* \brief span class based on ISO++20 span
*
* About NOLINTs in this file:
*
* If we want Span to work with std interface, like range for loop, the
* naming must be consistent with std, not XGBoost. Also, the interface also
* conflicts with XGBoost coding style, specifically, the use of `explicit'
* keyword.
