Let UI compute checksum instead of uploading the files to backend
Currently we upload the files, then backend computes the md5 checksum and finally it upploads the files to Minio only the file does not yet exist (the name of the files is the md5 checksum + an extension). But it would save time to let the UI compute the checksum, ask backend if it should send the files, and do so if needed only. https://stackoverflow.com/questions/768268/how-to-calculate-md5-hash-of-a-file-using-javascript
