Feature request: ability to edit dumps in app

[mxcdoam]

Right now it is only possible to edit Mifare classic memory dumps via built-in editor. To edit the other types of dumps user have to use a pc (with a pc app) or export-edit in a third party editor-import file back. This would be useful, since other types of emulatable/writeable credentials (for example Ultralight and SLIX) are sometimes used the same way as MFC, but lack a convenient editor.
