Marker data upload: Allow users to upload genotypic data in csv format

[aagulles]

Previous versions of Bioflow supported CSV file uploads where designations were represented as rows and markers/SNPs as columns, using a double-letter code format. To align with this structure, genotypic data downloaded from MDA tools in EBS was formatted accordingly. However, the latest version of Bioflow no longer supports this format, making it incompatible with genotypic data exports from EBS. Therefore, we kindly request that support be reinstated for CSV files structured with designations as rows and markers/SNPs as columns using the double-letter code format.
