Provide an error to properly indicate EOF

[ahicks92]

I'm integrating Symphonia, and the only thing I can find on detecting EOF is the symphonia-play example, which is going as far as a string comparison on an error message. It seems like either FormatReader's next_packet should return Option<Packet>, or there should be a top-level error. Hopefully this isn't a duplicate of something or docs I'm missing.

This is a very popular request, and one that I fully support. Since it's a breaking API change it will come in version 0.6. :)

Did I miss a duplicate ticket? I did look.

How involved would this be? If the answer is "not very" I may be willing to help, but I barely have time for my own projects as it is.

i think relevant would be #134

I've been working locally on some 0.6 features and have this prototyped. It works, though, there are some regressions I am ironing out. I'll push it to a 0.6 development branch once those issues are resolved.

This has now been implemented in the dev-0.6 branch!
