Change TVB EBRAINS Tumor Dataset Adapter

Currently we have a button to import EBRAINS Tumor data in TVB web, through a Creator, as these data were publicly available until recently, and no user input was necessary.

To get the data, now you need to ask for permission to EBARINS admins. You receive a personal link for download available 24h, and you need to agree to GDPR rules, as personal data is involved. Once you access that link, you may download only one file at a time. This means the user would need to manually recreate the structure by himself - highly prone to error.

We propose to change the Creator into an Importer. The user should recreate the dataset as close as possible to BIDS structure, them we will be able to import data. We will try to make the Importer as flexible as possible.
