Move hub drops last chunk of stdout when printing to Pybricks Code

[dlech]

Describe the bug
Not all of the expected text is printed on move hub. The last part is cut off.

To reproduce

Firmware v3.2.0b6-5-g45cc21fe.

1. Create a new program for a different hub (not move hub) using one of the templates in Pybricks Code.
2. Run the program on a move hub.
3. Observe the output in the terminal pane. The last bit is cut off.

Traceback (most recent call last):
  File "x.py", in <module>
ImportError: can't import name Techn

Expected behavior
It should not drop output.

Additional context

Capturing packets with Wireshark shows that the missing part was never sent, so the problem is likely with the Bluetooth chip/driver. Other hubs don't appear to have this problem.

This has been improved by the commit above, but not completely fixed (instead of happening every time, it now only happens after about 10 tries). We'll see how many other people hit this issue. Hopefully additional feedback will help better characterize the problem.

Here is a new sample program to more reliably reproduce the error:

from pybricks.pupdevices import Motor, Remote
from pybricks.parameters import Port, Direction, Stop, Button
from pybricks.tools import wait
from pybricks import version

print(version)

motor = Motor(Port.A)

# raises a TypeError due to bad stop parameter
motor.run_time(300, 1000, Stop, wait=False)

wait(1000)

Output is usually, but not always:

('movehub', '3.2.2', 'v3.2.2-414-ga42efda6-dirty on 2023-02-13')
Traceback (most recent call last):
  File "issue950.peError: 

Sometimes parts of the output are also repeated like this:

('movehub', '3.2.2', 'v3.2.2-414-ga42efda6-dirty on 2023-02-13')
Traceback (most recent call last):
  File "issue950.peError: 
eError:
