ZMQ_CONFLATE option appears to be unavailable in 6.0.0-beta.19 (using compatibility zeromq/v5-compat.js)

[sjlyoung58]

Importing ZMQ_CONFLATE gives undefined
I cannot access/use the ZMQ_CONFLATE option

Reproducing

import zeromq from 'zeromq/v5-compat.js';

const { ZMQ_SNDHWM } = zeromq; // Import the socket option constant
console.log(`ZMQ_SNDHWM = ${ZMQ_SNDHWM}`);
const { ZMQ_CONFLATE } = zeromq; // Import the socket option constant
console.log(`ZMQ_CONFLATE = ${ZMQ_CONFLATE}`);

output...

ZMQ_SNDHWM = 23
ZMQ_CONFLATE = undefined

Expected behavior
The import of ZMQ_CONFLATE should succeed and return an integer value

Tested on

• OS: Ubuntu 20.04 (Windows 11 WSL version: 2.1.4.0)
• ZeroMQ.js version: 6.0.0-beta.19

If I grep the zeromq src directory I get this which may be a clue (missing in src/compat.ts?)
