Send notifications with mp3 recording file attached

[grigolet]

Hello,
I am using telegram to send notifications for each detection. It is nice, but I found out that apprises support file attachments, so I wanted to try to send the record file together with the detection message.

I understand the code for the is in notifications.py L42, so I can play a little bit by modifying that function. However, it is not clear to me what is the path of the .mp3 recording associated. (maybe something related to the path variable?)
