Small bugfix (version 1.0.1)

It turns out the vibration strength ratio was sometimes accidentally applied multiple times, so if you use config vibe strength, that could cause pulses to be weaker than intended.

You can also now use config vibe strength with higher values — up to 26.
Keep in mind that 1.0 still means "full strength", so setting it higher than that enhances weaker vibrations, but also causes clipping of stronger ones.

I also fixed a small typo in the composer documentation, but chances are this was easy to miss already.
