This improves interop with certain string-like data structures, allowing to save extra allocation.

There was a problem hiding this comment.
I tried to fix this one by replacing const string& with std::string_view, but certain cases were broken.
I. e. HasSuffixString(const string&, const string&) stops working as it requires 2 implicit ctors (and the standard only allows one).
This could be simplified with C++20 starts_with / ends_with, but this is a long story.
