NullpointerException in TiledMapProperties

[Lutz89]

Hey @AristurtleDev 👋

There is an error in the implementation of the TryGetValue method in the TiledMapProperties class, which leads to a NullpointerException.

The assignment of the return value must be changed from
value = result ? null : tmpVal.Value;
To
value = result ? tmpVal.Value : null;

Cheers,
Lutz
