Library: add shortcut-ctor for own-member function

Browse source 
A common usage pattern is to derive from lib::Thread
and then implement the actual thread function as a member function
of this special-Thread-object (possibly also involving other data members)

Provide a simplified invocation for this special case,
also generating the thread-id automatically from the arguments

das macht nur den Code komplex, macht aber die Diagnostik nicht besser; std::invoke hat bereits gute Diagnostik (man mu&#223; sie nur lesen k&#246;nnen)
