Update piomaxlen.py change from 8192 to 8191 MAX_LINE_LENGTH (#4856)

Browse Source 
The maximum length of the string that you can use at the command prompt is 8191 characters.

This limitation applies to:

the command line
individual environment variables that are inherited by other processes, such as the PATH variable
all environment variable expansions
If you use Command Prompt to run batch files, this limitation also applies to batch file processing.
