[Feature Request] Poco::format does not recognize the `P` type

[Smurf-IV]

As per the standard types, P is supposed to dump a pointer address (As hex reference) into the string

But Poco::format does not (in 1.12.4 anyway !)

I think the only way this can possibly work is forcing the user to cast to void*.

Format.cpp

case 'p':
    str < std::hex << std::showbase << AnyCast<void*>(*itVal++);
    break;

Then the calling code would be:

int value = 0;
Poco::format("%p", static_cast<void*>(&value));

I don't believe it's possible to remove the static_cast because of the way Poco::Any works. Even if it were possible, it would require extra machinery inside Poco::Any to work.

@andrewauclair typed pointers are accessible, see testAnyPointer(), some accessors/detection has been added for 1.14. But I have no need, time or desire to add this feature and it's just creating noise - people post things then disappear, so I decided to close it

That sounds good to me. I've moved to using fmtlib myself.
