Enhancement: Add bool glob::match function

[shakfu]

While this library works as advertized.. (Thanks!), may I suggest to add a couple of bool functions which match a glob pattern or a vector of glob patterns against a given std::filesystem::path:

This is useful when one already has a pre-existing recursive filesystem iterator or algorithm.

This is a 'naive' implementation based on the pre-existing fnmatch function:

    bool match(fs::path name, std::vector<std::string> patterns)
    {
        for (auto& p : patterns) {
            if (glob::fnmatch(name, p)) {
                return true;
            }
        }
        return false;
    }
};
