Process arguments
'''

Create NeoPixel object with appropriate configuration.

Intialize the library

Next is the configuration related to TCP communication, where PORT is the defined port number, you can choose freely
from 0-65535, it is recommended to select the number after 1023, which needs to be consistent with the port number
defined by the client in the PC
