Be able to export / re-import exported CSV in the different sceens (and XLS)

Problem to Solve

In different screens (players, injects, organizations, etc.), it's possible to export the lines as a CSV.

This features covers:

• Be able to also export list in XLSX in addition to CSV
• Be able to import CSV/XLSX following the same format as exported

Do we still want to manage the XLSX export @Jipegien ? In terms of the current CSV implementation, we will take the XLSX files into account but transform them into CSV before import.

[Jipegien]

Not a problem to transform the xslx before import. Users must be able to import an xslx without having to transform it themselves.

Will it be possible to import injects without injects_id or audience_id into the tool - basically, if an organization passes an existing timeline in OpenEx format, will it be able to import it. (user's question)
