Output is written to the input file, with -o ignored

[Thunderforge]

Describe the bug/issue

When running kas, the output location (specified by -o) is ignored and output instead goes to the input file (specified by -f).

To Reproduce

1. In the command line at the project root, run make to generate the build directory
2. Run cd build
3. Run ./kas -o plugin.kdat -f "../examples/kdl/test.kdl" (per the Readme)

Note that the output is as follows:

Hello, World Saving data to ../examples/kdl/test.kdl

As you can see, the output was sent to the input file, overwriting it.

Expected behavior In the above example, I expect to see:

Hello, World Saving data to plugin.kdat

In other words, the output should go to what was passed in with -o.
