Deprecate npm package

[jimmywarting]

I think it have come to a time where we no longer need Safe-Buffer in modern day codes Think the npm package should be deprecated

Encourage ppl to use Uint8Array, TextEncoder, DataView instead 😉

I agree. This is both good and bad news.

After full deprecation, the repo should be archived

Not yet possible since many project still depends on it, like express

A temp solution is to npx nolyfill, which will do the work, and the code will not be affected.
