Transmission_main_example output changed

[ggrammel]

The output of $ python transmission_main_example is now more explicit in develop than what is shown in Readme. It looks now like this:

Transmission result for input power = 0.00dBm :
Transceiver Site_B
  OSNR ASE (0.1nm, dB):      32.03
  OSNR ASE (signal bw, dB):  27.95
  SNR total (signal bw, dB): 26.27
  SNR total (0.1nm, dB): 30.35

(No source node specified: picked Site_A)

(No destination node specified: picked Site_B)

Let's wait for #299 , then I'll update the asciicast.

@awgnxr, we've changed the code a few times since 2019, and these scripts are now generated on-the-fly when GNPy is installed, and therefore their location depends on the installation method. As a user, you can find them via:

• gnpy-transmission-example is a program that you can run directly instead of doing the former python transmission_main_example.py.
• the directory name where the default equipment library, example topologies, etc, are stored can be printed via executing gnpy-example-data

Here's where they are located in case you're a Python developer and would like to work on the code:

• The actual Python code which implements this example functionality is gnpy.tools.cli_examples.transmission_main_example().
• The example data are shipped in gnpy/example-data.
