Fix for "No module named camelot.ext" error

[balakumaranpalanivel]

When i followed the instructions using excalibur I ran into the following issue.

Traceback (most recent call last): File "/Users/balakumaranpalanivel/.pyenv/versions/3.7.9/bin/excalibur", line 5, in <module> from excalibur.cli import cli File "/Users/balakumaranpalanivel/ReposPersonal/excaliburRoot/excalibur-fork/excalibur/cli.py", line 8, in <module> from .tasks import split, extract File "/Users/balakumaranpalanivel/ReposPersonal/excaliburRoot/excalibur-fork/excalibur/tasks.py", line 9, in <module> from camelot.ext.ghostscript import Ghostscript ModuleNotFoundError: No module named 'camelot.ext' 

There seems to be multiple different ways to fix online.
But the root cause seems to be this commit where the ext folder was removed in camelot but excalibur continues to use it.

This fix seems to be the most popular one based on stackoverflow upvotes and makes sense to me.
But please correct me if am wrong.

P.S - I had a look at contributing guidelines, i hope i did not miss anything 🤞
