GSEApy: Enrichr: Local mode of GO/enrichment analysis does not provide Odds Ratios in the results

Hi, thanks for this package! This is more of a feature request than a bug report. I think the odds ratio is quite an important value to interpret enrichment analysis results.

Setup

I am reporting a problem with GSEApy version, Python version, and operating system as follows:

import sys; print(sys.version)
import platform; print(platform.python_implementation()); print(platform.platform())
import gseapy; print(gseapy.__version__)

3.9.5 (default, Jun 4 2021, 12:28:51) [GCC 7.5.0] CPython Linux-3.10.0-1062.18.1.el7.x86_64-x86_64-with-glibc2.17 0.10.5

Expected behaviour

When using the Enrichr functionality of GSEApy gseapy.enrichr() in local mode, to be able to provide a custom background gene set, the resulting data frame contains the same columns (including odds ratio) as in the vanilla mode (direct query of enrichr).

Actual behaviour

When using the Enrichr functionality of GSEApy gseapy.enrichr() in local mode, to be able to provide a custom background gene set, the resulting data frame does not contain Odds Ratios, although the vanilla mode returns Odds Ratios from enrichr.

Steps to reproduce

It is already apparent in the respective example in the docs.
