add replay test for atrac3+ audio played in multiple addStreamData calls

[elsonLee]

This test is written for testing atrace3+ audio replay, the data stream will be feed into audio engine several times, according to the buffer writable room. It is not limited to 10s.

Normally we add the prx and expected files (generated by gentest.py) as well, so we know what should be compared against for the emulator.

Is the at3 file one that's okay to distribute? If not, maybe we can use #82?

Thanks for adding this.

@unknownbrackets , I get it, I'll replace the at3 file and update prx and expected files, Thank you.

The sample.at3 file can be replaced to other at3 file and the most strange thing is when decoding the last part of data the remain frame value always returned as a minus value, I have no idea why.
