[Bug] cortexneurons/clamav_fileinfo no clamd installed

Describe the bug

The dockerized cortexneurons/clamav_fileinfo fails to scan with ClamAV. The error indicates either ClamD is not running or installed.

root@057dc1cabc74:/opt/cortex# docker run -it --rm --entrypoint bash cortexneurons/clamav_fileinfo:1
root@be1203e87504:/worker# /bin/sh -c ClamAV/pyclam_analyzer.py
Traceback (most recent call last):
  File "/worker/ClamAV/pyclam_analyzer.py", line 7, in <module>
    cd = pyclamd.ClamdUnixSocket()
  File "/usr/local/lib/python3.10/site-packages/pyclamd/pyclamd.py", line 709, in __init__
    raise ConnectionError('Could not find clamd unix socket from /etc/clamav/clamd.conf or /etc/clamd.conf')
pyclamd.pyclamd.ConnectionError: Could not find clamd unix socket from /etc/clamav/clamd.conf or /etc/clamd.conf

To Reproduce
Steps to reproduce the behavior:

1. configure cortex to use docker analyzers
2. enable the the clamav Analyzer
3. try to scan a file.

Complementary information
Is there a way to resolve this locally on the dockerized container and have the changes stick? As it seems that If i try and resolve this (by installing ClamD and configuring) directly on the container, the changes get wiped when re-running the analyzer. (i assume this is due to it pulling a fresh server each time)

Also, what would be the best approach to using custom signature files when using the dockerized container? would it be best to simply map the signature location to the host? or would it be to add them on a customized clamav docker container?
