BigInt / BigInt64Array / BigUInt64Array

[kawanet]

Node.js supports BigInt BigInt64Array BigUInt64Array which are proposed at stage 3 at TC39.

$ node -e 'console.log(typeof 1n)'
bigint

$ node -e 'console.log("" + 9007199254740993)'
9007199254740992

$ node -e 'console.log("" + 9007199254740993n)'
9007199254740993

We currently have int64 option to decode msgpack's (u)int64 with int64-buffer object.

var codec = msgpack.createCodec({int64: true});

Features:

• BigInt decoding with new {bigint: true} option.
• BigInt encoding per default.
• extension types for BigInt64Array and BigUInt64Array
