Potential issue

[grill2010]

Hi, I use the library in my streaming app and I encountered a potential issue, at some point very rarely my app was crashing so I started to investigating this problem and I found out it crashes here

https://github.com/Dario-Gasquez/swift-opus/blob/b763c399014eb6260a9bfe2f843677a4b4fd435b/Sources/Opus/Opus.Decoder.swift#L59

because the output variable was 'none' and the reason is that sample count returned 0 before ->

let sampleCount = opus_decoder_get_nb_samples(decoder, input.baseAddress!, Int32($0.count))

There was a pull request which added a check for this

#9 (review)

But this check should it not rather be

if sampleCount < 1 {
     throw Opus.Error(sampleCount)
}

as otherwise there will be a crash?
