`element_data_loader` is non-existent in this repository

element_data_loader is required both in the requirements.txt file and the documentation. Otherwise trigger won't work.

Thanks @tdincer. The pull request linked above now documents the installation instructions for element-data-loader.

We opted not to put element-data-loader in the requirements.txt of workflow-calcium-imaging, because we have configured element-data-loader to allow for installation of optional packages that are not on PyPI, such as CaImAn and scanreader. This is done using the extras_require feature in setup.py. The user would manually choose which optional packages they wanted to install and follow these installation instructions. Thus installation of element-data-loader would be an extra installation step outside of requirements.txt.
