    Fix the type of ar_card_theme_qsvg_get_card_aspect
    
    For some unknown reason the build only fails for me
    on arm.
    
    ar-card-theme-qsvg.cpp: In function 'void ar_card_theme_qsvg_class_init(ArCardThemeQSvgClass*)':
    ar-card-theme-qsvg.cpp:336:32: error: invalid conversion from 'qreal (*)(ArCardTheme*) {aka float 
(*)(_ArCardTheme*)}' to 'double (*)(ArCardTheme*) {aka double (*)(_ArCardTheme*)}' [-fpermissive]
