download using aiohttp fails on python 3.9 with too many requests error

[cokelaer]

The code works perfectly well for pyton 3.8 and python 3.10

How to reproduce. With a sequana pipeline under a conda environment py3.9

pip install sequana_nanomerge
sequana_nanomerge --use-apptainer 

also note that using manual requests of the apptainers works so the 'too many requests' error is not relevant. looks like a aiohttp issue but could not find any solution. Tried using ssl.certifi on the TCPconnect. Tried disabling ssl. no solution so far.
