make_pct_string_view | Return a valid percent-encoded string.

Objects of this type behave like a `core::string_view` and have the same interface, but offer an additional invariant: they can only be constructed from strings containing valid percent-escapes. Attempting construction from a string containing invalid or malformed percent escapes results in an exception.

###### Operators

The following operators are supported between `pct_string_view` and any object that is convertible to `core::string_view`

    bool operator==( pct_string_view, pct_string_view ) noexcept ;
    bool operator!=( pct_string_view, pct_string_view ) noexcept ;
    bool operator<=( pct_string_view, pct_string_view ) noexcept ;
    bool operator< ( pct_string_view, pct_string_view ) noexcept ;
    bool operator> ( pct_string_view, pct_string_view ) noexcept ;
    bool operator>=( pct_string_view, pct_string_view ) noexcept ;

###### Description

This is the type of value returned when iterators of the view are dereferenced.
