 * **Can read `smpl` chunk data from files that contain this kind of chunk.** If a *.wav file contains a `smpl` chunk, then `Reader.sampler_info` will return a `SamplerInfo` instance with the relevant data (or `nil` otherwise).

 * **More informative errors raised by `Reader.new`**. When attempting to read an invalid file, the error message now provides more detail about why the file is invalid.
