feat: improved global instance

[noomorph]

Adds bunyamin and nobunyamin named exports.

These root logger instances receive a shared threadGroups config option to facilitate traceEventStream creation by the end consumer of Bunyan logs. Libraries using bunyamin can push their thread groups (id, name, maxConcurrency) to provide a better experience when browsing the final trace log in Chrome Tracing or Perfetto UI.

import bunyamin from 'bunyamin';

bunyamin.threadGroups.push({ id: 'mylib.emitter', displayName: 'Emitter (mylib)' });

And then, the final consumer:

import { createLogger } from 'bunyan';
import bunyamin, { traceEventStream } from 'bunyamin';

bunyamin.logger = createLogger({
  name: 'my-app',
  streams: [
    {
      level: 'trace',
      stream: traceEventStream({
        filePath: '/path/to/trace.json',
        loglevel: 'trace',
        threadGroups: [...bunyamin.threadGroups, { id: 'custom-thread' }],
      }),
    }
  ],
});
