Setting output to another pts gives error on Ubuntu 20.04

Hi,

first, thanks for your really helpful project, I love and use it a lot.

Usually I use manjaro for my daily work, but at the moment I am forced to use WSL2 with Ubuntu 20.04 on my company laptop.

When trying to set the output to another pts, I get the following error:

Cannot write the dashboard
Traceback (most recent call last):
File "<string>", line 504, in render
TypeError: write() argument 1 must be unicode, not str

every time the dashboard gets refreshed.

I also tried it on another PC with native kubuntu 20.04.

I do the following with gdb-dashboard v0.13.0 from git:

• open a new terminal with xterm, get the number with tty -> e.g. /dev/pts/6
• start gdb session for arm (arm-none-eabi-gdb)
• dashboard variables -output /dev/pts/6
• Seems to be ok
• step
• The error occurs and nothing is put on the terminal

It does not matter if I set the output for variables or anything else. I tried xterm and konsole.

Please tell me if you need more information

The bin with python-support is called arm-none-eabi-gdb-py

For me, the py2-version works as well. Thank you for the fix. Nevertheless I will stick to the py3-version of GDB.
