Feature Proposal (+current workaround): choose soundfiles on your computer as sounds

[sray]

It would be great to be able to simply select "custom sound" and then provide the filepath to it on my computer.

My current workaround to achieve this:

1. Find out what my profile path is by visiting chrome://version/
2. find out which into which extension folder inside $PROFILE_PATH/Extensions/ the marinara extension is installed into using ls -l $PROFILE_PATH/Extensions/* | grep -B 3 $MARINARA_VERSION (current version is 32)
3. Replacing an mp3 inside $PROFILE_PATH/Extensions/$MARINARA_DIR/32_0/audio with my custom mp3.
4. Finding out the name of my now custom mp3 on the UI by looking into https://github.com/schmich/marinara/blob/master/src/Sounds.js
5. selecting the sound in the Marinara options UI
