Return a `bsl::string_view` object referring to the first occurrence in (the referent data of) the specified `string` at which (the referent data of) the specified `subString` is found using case‐insensitive comparisons, or `bsl::string_view()` if there is no such occurrence. See {Caseless Comparisons}. If `subString` has zero length then a zero‐length reference to the beginning of `string` is returned (i.e., `bsl::string_view(string.data(), 0)`);
