Command line speedtest not working

[potsmugen]

Describe the bug

Running Ikemen with speed, speedtest or stresstest arguments (maybe others) causes a Lua crash. Maybe it was the game speed refactor?

To Reproduce

1. Run Ikemen from command line with those arguments

Expected behavior

Same as previous builds.

Even weirder, commenting out the call mentioned in the error message:

if main.flags['-speedtest'] ~= nil then
	--setGameSpeed(100 * gameOption('Config.Framerate'))
end

Just results in Ikemen starting as if there was no command line argument at all. setGameSpeed is definitely broken though; even a simple setGameSpeed(100) causes the same error.

The error itself is caused by the removal of the setGameSpeed function here: db7ecbf

Not sure if it can just be added back or if it also needs a refactor to match new speed settings.
