[BUG] Encoding Argument While Loading Pickle File Produces Error in pyscenic aucell

[ggruenhagen3]

When trying to input a pickle (dat) file of regulons for pyscenic aucell, I got the following error: pyscenic.cli.pyscenic - ERROR - binary mode doesn't take an encoding argument. This is due to line 33 of ctxcore/genesig.py, which should be changed so that an encoding argument isn't used like so return open(filename, mode).

Version information: pyscenic 0.12.1, python 3.9.18, pickle 4.0. Executed on a HPC running CentOS Linux 7.
