[FEATURE] Headless benchmark

[V10lator]

Hi, I'm using your mod on a le potato ( https://libre.computer/products/boards/aml-s905x-cc/ ). Ofc. I want as much resources for Java as possible, so the complete thing is flashed with a headless image and there's no input/output method except SSH (or UART). Now when I try to start BetterFPS standalone I get this:

libre@libre-computer:~/forge-server-1.12.2$ java -jar mods/BetterFps-1.4.8.jar
Loading en_us...
Waiting for Swing to load...
Exception in thread "main" java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper
        at java.awt.Toolkit.loadAssistiveTechnologies(Toolkit.java:807)
        at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:886)

        at guichaguri.betterfps.installer.BetterFpsInstaller.main(BetterFpsInstaller.java:48)

So my question is: Could you please make at least the benchmarks available from headless? Maybe a simple startup argument like --headless (java -jar mods/BetterFps-1.4.8.jar --headless) will be enough?

Would the server command option "nogui" work for you here?

EDIT: Apparently not. It looks like the performance is pretty much identical between all of them other than Java's own implementation though so I wouldn't worry about it.

+1 would be very nice to have.
