Handshake failure error when used with Python 3.10

[ManavalanG]

I ran into error when using igv-reports with Python 3.10. Here is what I tried to resolve the issue:

• Installed igv-reports using conda. I didn't specify or pin python version here. Config file used:

name: igvreports

channels:
  - conda-forge
  - bioconda

dependencies:
  - igv-reports==1.7

• Conda installed python 3.10. I don't have specific version info beyond this as I deleted the conda env during debugging :)

• igv-reports ran into error when test command was run.

• I didn't see any igv-reports specific code in the error message. So I hypothesized python version may be the issue here and then chose to pin the python ver 3.8 in conda env.

name: igvreports

channels:
  - conda-forge
  - bioconda

dependencies:
  - igv-reports==1.7
  - python=3.8

• Test command ran successfully in the new created conda env

Thanks for the report, we will update the python requirement to 3.8.
