use Buffer.from if available

[ARitz-Cracker]

new Buffer is deprecated, so Buffer.from should be used if it's available

This would be very nice to have :) @creationix?

This is great, but there is no need to check every time the function is called. Instead of having the indirection that checks at runtime every time the function is called, simply set the function.

// Use Buffer.from directly if it exists.  Otherwise, create a version of the constructor that works like a function.
const bufferFrom = Buffer.from ? Buffer.from : (...args) => new Buffer(...args);
