Making NetEq bitexactness test independent on reference files.
Making NetEq bitexactness test independent on reference files.

NetEq bitexactness test depended on reference files which differs from platform to platform. This makes it very hard to update Neteq.

New method maintains the ability to save output into files. But it verifies the checksum only. With this, when bitexactness test fails, we can still check closely to the output file if need, but the test becomes much easier to modify.
