Description
Describe the bug
The SizedRotatingLogger has an error in the _default_name. When the rollover occurs, files such as file.log_2022-08-27T111103_#000.gz are created. When reading these files with LogReader, a ValueError is thrown, indicating No read support for this unknown log format ".log_2022-08-27t111103_#000".
To Reproduce
Socket CAN setup
Enable CAN interface:
sudo ip link add dev vcan0 type vcan && sudo ip link set up vcan0
Generate random CAN messages 1 millisecond apart:
cangen vcan0 -e -I 18EAFF26 -L i -v -v -v -g 1
python-can setup
python -m can.logger -c vcan0 -i socketcan -b 250000 -f file.blf.gz -s 150000
Use can.logconvert
(pycan) jackcook@rollo:~/Documents/python-can$ python -m can.logconvert file.log_2022-08-27T111103_#000.gz file.log

) from None
ValueError: No read support for this unknown log format ".log_2022-08-27t111103_#000"
Expected behavior
The SizedRotatingLogger should adequately parse the suffix and create log.gz files.
