Extra-headers are not being passed in query() call

Hi, thanks for this client package.

We are experiencing an issue with passing extra headers at the trinoClient.query({...}) stage. When we create the client with the extra headers, everything works as expected. However, the issue arises when we attempt to pass the extra headers in the query() call; something happens along the way, and this parameter is either ignored or overwritten.

Everything works:

const trinoClient = Trino.create({
  server: url,
  extraHeaders: {
    'X-extra-header': 'example-header-value'
  }
});
trinoClient.query({query: '...'});

Extra headers are ignored/overwritten:

const trinoClient = Trino.create({
  server: url
});
trinoClient.query({query: '...', extraHeaders: {'X-extra-header': 'example-header-value'}});

The extra header is dynamic value, so we can't use it once on the client creation; in addition we don't want to create a new client on every query. BTW, everything works as expected in the python client package.

Thanks
