tool ignores baud rate

[GTP95]

After flashing the firmware, my module is listening on ttyUSB0 at a baud rate of 9600 baud (checked with serial terminal), so I'm trying to connect to that port using that baud rate, but nodemcu-uploader seems to simply ignore the parameter I pass on terminal, here is a sample output:
`$nodemcu-uploader -b 9600
opening port /dev/ttyUSB0 with 115200 baud
Traceback (most recent call last):

nodemcu_uploader.exceptions.CommunicationTimeout: Timeout waiting for data

During handling of the above exception, another exception occurred:

I installed your tool via PyPy, my os is Netrunner (based on Arch Linux) and the --version switch gaves this output:
nodemcu-uploader 0.4.3 (serial 3.3)
