Expanding upon the read::Description struct - what kind of info do we want to provide?

[mitchmindtree]

Currently, the read::Description provides:

• The number of channels via channel_count().
• The rate at which the audio is sampled per channel via sample_rate().
• The audio Format via format() as of Move method for returning Format from Reader to Description #4.

Some other useful information might include:

• Whether the channels are interleaved or not. If we end up providing unique methods on the Reader for producing InterleavedSamples and NonInterleavedSamples, this could be a useful indicator for determining the more efficient option?
• Whether the sample is formatted as integer or floating point data.
• The bit depth per sample. Users who care highly about performance could match on this alongside the sample format to request the most efficient target Sample type when calling Reader::samples.

Also, maybe providing metadata would be an idea. Maybe though through a different function.
