headless broken in 0.4.0

[bdale]

As I work on adding an autopkgtest for the Debian package, I'm having trouble making headless mode work. I tried to just use one of the existing test motor definitions, and it fails like so:

bdale@rover:~$ openmotor -h debian/openmotor/test/data/real/o3100/motor.ric

I have no idea if it is the correct fix.

Hi. Any hope for a new release with a fix for this problem?

[reilleya]

Hi Petter, with the chip shortage putting some of my other projects on hold, I have been planning to clean up the last few things for v0.5.0 and release it. This will definitely make it in when I do! I am working on finishing support for grains with conical cores, which is the last major feature planned for the release.

Should be fixed on staging, will make it into v0.5.0 soon.
