Change AudioResampler's source quality.

Original commit.
commit ac6020508acedd316391dee42329040bf45f8d90
change ID ac602050
Some part of commit messages 'Very high quality is enabled only for 44.1 -> 48 or 48 -> 44.1, and uses low quality for all other use cases.'

But there are no codes for enabling 'Very high quality'.
So, I changed DEFAULT_QUALITY to VERY_HIGH_QUALITY to follow the intent of the author.
