Add custom logger

[ngxson]

Resolves #40 #17

When initializing Wllama, you wan pass a custom logger to Wllama.

Example 1: Suppress debug message

import { Wllama, LoggerWithoutDebug } from '@wllama/wllama';

const wllama = new Wllama(pathConfig, {
  // LoggerWithoutDebug is predefined inside wllama
  logger: LoggerWithoutDebug,
});

Example 2: Add emoji prefix to log messages

const wllama = new Wllama(pathConfig, {
  logger: {
    debug: (...args) => console.debug('🔧', ...args),
    log: (...args) => console.log('ℹ️', ...args),
    warn: (...args) => console.warn('⚠️', ...args),
    error: (...args) => console.error('☠️', ...args),
  },
});
