add athan volume and azan preview features #166
Description
assalamualaikum, first of all i would like to thank you for the amazing app been using it for some time and it seems pretty solid but i think it needs a feature where you can adjust the volume that the azan will sound like because the app relies on both the alarm and media volume so i think it will be nice to add an option to adjust how loud the azan will sound , also i think the app needs an option to preview the azan and test it before the next prayer .
(sorry for the bad english tho)
again thank you for the fantastic app , may allah grant you janna
بارك الله فيكم
