drag and drop of path stopped working in terminator version 2.1.3

[pvdam3]

Describe the bug
Since the update to v 2.1.3, dragging and dropping of files and directories in order to directly paste the path in the terminal stopped working. I checked v2.1.2 and v2.1.1 and in both cases, this functionality was still there. This functionality was added in v2.1.0 (#159).

To Reproduce
Steps to reproduce the behavior: select a file or folder and drag it into the terminal window

Expected behavior
the shell should paste '/home/peter/Downloads'

Desktop (please complete the following information):

• OS or Linux Distribution: ubuntu 20.04
• Version 20.04
• Display Technology: X11

Additional context
When running terminator from a ubuntu terminal, I see the following error message appearing:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/terminatorlib/terminal.py", line 1264, in on_drag_data_received
    term.feed(txt.encode())
  File "/usr/lib/python3/dist-packages/terminatorlib/terminal.py", line 1697, in feed
    self.vte.feed_child(text.encode())
AttributeError: 'bytes' object has no attribute 'encode'

N.B. thanks for your great work!
