Please support FPR files as attachment

[ArsArmandi]

Bug description / Feature request
When trying to upload the fortify FPR file to the test, i get the error "{"non_field_errors":["Unsupported extension. Supported extensions are as follows: .txt, .pdf, .json, .xml, .csv, .yml, .png, .jpeg, .sarif, .xlsx, .doc, .html, .js, .nessus, .zip"]}". In my usage i always attach the files of a scan to the test itself. FPR files are supported by DefectDojo, but it is not possible to upload the FPR file as attachment. Can you add .fpr to the list of allowed files for attachments?

Steps to reproduce
Steps to reproduce the behavior:

1. import an Fortify Scan
2. Upload a FPR file to the import scan

Expected behavior
I would like DefectDojo to accept the uploaded FPR File.
