Add water hose sounds

[hitshydev]

Changes

I've added two new sounds that I find quite calming when combined.
I had some trouble finding names that suit the sounds well, some feedback would be nice.

Testing

• Tested on a physical device
• Added or modified unit test cases

@hitshydev I didn't get the time to properly test out the new sounds. But from the very first listen the water hose sound did seem to have some abrupt transitions. Also I am not sure if I am correctly recognising the water hosing sound. I'll test it out more. I think I'll need to resample the water hose sound. I am not sure about including the hosing sound though.

Sorry for the delay on merging this. I have decided to defer all sound related change to 0.9.x. Considering #62 which would require rework on this if I merge it now.
