Update readable-stream and tape

[shinnn]

Especially, readable-stream update helps better dependency deduplication while using npm v3.x.

I can see a reason why deps should be ~, but for dev deps it should be safe to use ^.

@maxogden @mafintosh What do you think?

@shinnn 👍 - feel free to update them to ^ actually. Then we don't need to bump them that often and both readable-stream and tape follow strict semver

[shinnn]

@mafintosh Thanks for the response. I'll update the PR soon.

@mafintosh What do you think about other dependencies, inherits and typedarray?

[mafintosh]

@shinnn yea update those as well! :)
