make rx-stomp-rpc ESM conform

[Michael-Stade]

Including @stomp into an Angular17 project is leading to following warning:

• [WARNING] Module 'uuid' used by 'node_modules/@stomp/rx-stomp/esm6/rx-stomp-rpc.js' is not ESM
• CommonJS or AMD dependencies can cause optimization bailouts.
• For more information see: https://angular.io/guide/build#configuring-commonjs-dependencies
  I could fix this in file rx-stomp-rpc.js by replacing:
• import { v4 as uuid } from 'uuid';
  by insert the v4() function from the uuid module (and rename it to "uuid").
  But because the files in the esm6 folder are not subject of changes here, please find a solution to fix it
  Best regards

Thank you for your report. I need clarification about your changes. Please let me know the older version and what you replaced it with. Better yet, please submit a PR (even if you directly update the files in the esm6 folder).

Because the token I created didn't got accepted, here what I did:
In rx-stomp project: file esm6/rx-stomp-rpc.js:

import { filter, first, Observable } from 'rxjs';
//import { v4 as uuid } from 'uuid';

/**

• This uuid() function is a copy (and re-naming) of the the v4() function from uuid/v4.js
• it removes the following warning by Angular17:
• [WARNING] Module 'uuid' used by 'node_modules/@stomp/rx-stomp/esm6/rx-stomp-rpc.js' is not ESM
• CommonJS or AMD dependencies can cause optimization bailouts.
• For more information see: https://angular.io/guide/build#configuring-commonjs-dependencies
• make rx-stomp-rpc ESM conform make rx-stomp-rpc ESM conform #549

  var i = buf && offset || 0;

if (typeof(options) == 'string') {
buf = options === 'binary' ? new Array(16) : null;
options = null;
}
options = options || {};

var rnds = options.random || (options.rng || rng)();

rnds[6] = (rnds[6] & 0x0f) | 0x40;

// Copy bytes to buffer, if provided
if (buf) {
for (var ii = 0; ii < 16; ++ii) {
buf[i + ii] = rnds[ii];
}
}

return buf || bytesToUuid(rnds);
