Title: Add mute fuctions for one sound in OALSimpleAudio

I'm developing a musical book, so didin't find functions to mute one sound using OALSimpleAudio, so I added tree functions to solve it.

-
```objective-c
/*
switch beteen mute and unmute.
@param filePath The path containing the sound data.
*/
- (void) switchMuteWithEffectName:(NSString*) filePath;
```
-
```objective-c
/*
only mute the effect.
param filePath The path containing the sound data.
*/
- (void) muteEffectWithName:(NSString*) filePath;
```
-
```objective-c
/*
only unmute the effect.
param filePath The path containing the sound data.
*/
- (void) unmuteEffectWithName:(NSString*) filePath;
```
