Big files in datawizard lead to NotReadableError

[ebroda]

Description of the issue

If you open https://openenergyplatform.org/dataedit/wizard/.
And upload a BIG CSV file (> 1 GB) (e.g. File)
The platform returns a NotReadableError: File could not be read

Expected behaviour would be that the platform can handle the dataset.

Steps to Reproduce

see above

Ideas of solution

Probably there are some issue in regard to the file size on reading the csv file. Maybe we need to find a way to have smaller chunks.

I am inclined not to fix this.

• One problem is the limitations of the browser to load the file
• It would take a VERY long time and is not practical - the primary method for large datasets should be the API.

I'm fine with that. As this report is more than a year old, I'm not sure if and which kind of error message exactlywas there.

I think if you catch this case and show a good, human-readable error message ("to big, use API"), that's also totally fine.
