Deprecated Buffer API

[kibertoad]

This library uses new Buffer, which is deprecated. Buffer.allocUnsafe should be used instead

Would you be open to a PR fixing this?

[brianloveswords]

I'd be open to that PR!

@brianloveswords Thank you! Since Travis CI stopped working long time ago (and is no longer a good option for OSS), I've opened a PR to add GitHub Actions CI, to ensure that changes won't break anything: #21

@brianloveswords I only now realised that you actually have a check in your code already that only uses old API for old Node versions. Do you still intend to support all of Node versions, or you are open to releasing a new semver major dropping support for anything below Node 8?

[brianloveswords]

@kibertoad I'm open to a major bump that drops old versions

fixed by #27
