Better documentation with the examples

alsa-project/tinycompress issue #8 was opened from Andres6936:

I have compiled the program and when I run the `cplay` script I get an error:

```shellsession andres6936@Tierra ~/CLionProjects/tinycompress-master/src/utils $ cplay TestAudio.mp3 Error: Can't find sync word ```

I have already checked out different mp3 files and I keep getting the same error. I have also tried different options, but it is always the same error.
