Warn if --audio_sample_rate does not match training sample
...
In PR #2688 , we started specifying the upper frequency limit when computing Mfccs.
This value was computed as half of the --audio_sample_rate value. Despite accepting
a variable sample rate input for the Mfcc computation, the TensorFlow OP only takes
a constant upper frequency limit, so we can't pass a dynamic value computed from each
sample to the op.
This means we lost the ability to transparently train on data with multiple sample
rates. This commit adds a warning message in case a training sample does not match
the --audio_sample_rate flag.
