Issues when using ftplib on ESP32 together with Micropython's built-in "requests" module

[PV-autarky-optimizer]

I tested micropython-ftplib with Micropython on my ESP32 and it works well. That is the good News.

I found ftplib is incompatible to Micropython's intrinsic library requests for ESP32. I have Micropython v1.24.1 installed via Thonny IDE. It's a pitty.

My Micropython code is like this:

import network                  # This library provides WLAN
from ftplib import FTP as FTP   # FTP Client from github.com/SpotlightKid
import requests as requests     # This library belongs to Micropython and carries out GET requests in the HTTP protocol. 
... setup_WLAN() ... 
response = requests.get('https://s18.myenergi.net/cgi-jstatus-*', headers = {'User-Agent': '...'}, auth = None, timeout=20)

As soon as ftplib is imported, requests.get fails to access the internet and after timeout it returns the error [Errno 116] ETIMEDOUT.

This incompatibility occures both with ftplib.py and esp/ftplib.py

By the way, in ftplib.py, line 353, fix the bug by changing b'\n' to '\n'.
