The xmrig priority setting does not work.
Version xmrig 6.16.4, when run from the command line with the `--cpu-priority 1` parameter, the priority of the process xmrig.exe it remains "normal", although it should be "very low". The same with the `--cpu-priority 0` parameter
Tested on Windows 7 and windows 10

It also doesn't help to edit the registry to:
```
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\xmrig.exe\PerfOptions]
"CpuPriorityClass"=dword:00000001
```

What could be the problem?

P.S. When setting the parameter 
`"priority": 0`
in config.json process priority setting works correctly
