We had to wait many years for it, but finally we have a starts_with()
method in C++20. Let's use it instead of ugly substr()-based code.
This is probably not a performance gain - substr() for a string_view
was already efficient. But it makes the code easier to understand,
and it allows us to rejoice in our decision to switch to C++20.
