Requirements install error

[kathryn-ods]

I'm following the instructions here https://github.com/GFDRR/rdls-spreadsheet-template?tab=readme-ov-file#developer-documentation
When I get to pip install -r requirements.txt I get an error

Processing /mnt/9E863086863060C7/GDrive/Work/Repositories/risk_data_library/rdls-spreadsheet-template/flatten-tool (from -r requirements.txt (line 31))
ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: '/mnt/9E863086863060C7/GDrive/Work/Repositories/risk_data_library/rdls-spreadsheet-template/flatten-tool'

I think I can temp fix this by just removing flattentool from requirements and installing separately for now.

Ah yes, looks like it is trying to install Flatten Tool from my local drive. I'll update the requirements file in the repository.

@kathryn-ods I've fixed the issue in #20
