New package: furnace

[ChunkyHamsterfly]

Although I had requested the package at #1420, I eventually decided to try adding it myself.

Please note that this is my very first pull request ever and I don’t even know if it builds, so if something goes wrong, please let me know or maybe cancel it.

As you see, your app don't build on TUR environment.

CMake Error at CMakeLists.txt:308 (add_subdirectory):
The source directory

/home/builder/.termux-build/furnace/src/extern/portaudio

does not contain a CMakeLists.txt file

Tried to disable portaudio to see if it at least proceeds past the error (I don't think the dependency is necessary anyways).

Sorry, I forgot this pull request existed. Now that I updated the source code link to point to version 0.6.8.3, can we try building it again and see if it works?

Closed due to inactivity.
Feel free to use my buildscript if you want (I think it's also covered by the GPL), but change the maintainer's name. Nevermind, I'll be opening a new PR in the next days, once I learn about buildscripts better (opened #2066).
