Spam of messages each time on reload using UPM + samples

[novavision]

Hey.

First of all, thanks for the great asset.

I installed it using UPM and also downloaded 3D samples. Unfortunately each time on Editor reload I have around 10 messages in console with the same text

A meta data file (.meta) exists but its folder 'Packages/com.mitay-walle.phys-sound/Samples/Samples3D~' can't be found, and has been created. Empty directories cannot be stored in version control, so it's assumed that the meta data file is for an empty directory in version control. When moving or deleting folders outside of Unity, please ensure that the corresponding .meta file is moved or deleted along with it.

Had to remove from UPM and install using a .unitypackage

Just a minor feedback - I planned to use your phys sound system but I would merge it with another sounds controller system (playing just an AudioSource is not enough for most of мy cases). I found that using UPM package there are not much virtual methods to override for better control. Would be great to have more flexibility. Maybe, create some base method to override, and in your particular samples just use child class with AudioSource as a main tool to play the sound.
