Add paramiko and pywin32 to requirements

from escpos.printer import Usb
LOG: paramiko module not found!
LOG: Missing win32 lib!

Add paramiko and pywin32 to requirements.txt and do setup easier :) . Until then:

pip install paramiko
pip install pywin32

Hi, thank you for the issue. I don't quite understand why paramiko is needed for the USB-driver?

Might be windows related, I was unable to use the library on Windows with my pip setup that worked on Linux. Didn't look into it further though.
