LDC 1.13.0

[kinke]

Glad to announce LDC 1.13:

* Based on D 2.083.1.
* The Windows packages are now fully self-sufficient, i.e., a 
Visual Studio/C++ Build Tools installation isn't required anymore.
* Substantial debug info improvements.
* New command-line option `-fvisibility=hidden` to hide 
functions/globals not marked as export, to reduce the size of 
shared libraries.
