Can't run pymodbus.simulator --help

Description

Trying to run pymodbus.simulator --help fails:

<coroutine object main at 0x7efcc073cf90>
sys:1: RuntimeWarning: coroutine 'main' was never awaited
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

The main function used as entry point for the simulator is an async function:

pymodbus/pymodbus/server/simulator/main.py

Line 113 in 12859d0

async def main():

It can't be used directly as an entry point. The entry point should be a function using asyncio.run.

Looks like a bug, but the workaround is simple.

Thanks for the quick fix!
