Unsafe use of `this.cache.hasOwnProperty`

[kopertop]

I started receiving errors about this.cache.hasOwnProperty is not a function. Digging into the code it looks like tokenizer.ts uses a bit of unsafe code considering this.cache is a map that allows any passed in value to be used as a token:

    if (this.cache.hasOwnProperty(token)) {
      return this.cache[token];
    }

Instead, this should be:

    if (Object.prototype.hasOwnProperty.call(this.cache, token)) {
      return this.cache[token];
    }

I'm also having this issue, would appreciate it if the PR was merged soon 🙏
