--forceupdate doesnt work multithreaded.

Is your feature request related to a problem?

--forceupdate doesn't work multithreaded and it's too slow for updating big worlds. updateing 15k*15k world took 30 minutes.

Describe the solution you'd like.

make the world updater update chunks parallel not sequentially.

Describe alternatives you've considered.

there is no alternatives.

It already is threaded, but the math for determining cores could maybe be less restrictive
int threads = Runtime.getRuntime().availableProcessors() * 3 / 8;

It may be worthwhile to add a startup flag to control the number of threads.

I thing math needs to be improved becouse i give 8 cores to the folia for test and it peaked at 400%(1 core=100%) its half the max speed of my hardware. Btw when i give 16 cores it peaked at 1000%(1 core=100%).
