Buffer.x and Buffer.y are not updated in realtime

[p3nt4]

This might be related to #2021
Apologies if I am not using the api correctly.

Details

• Chrome: Version 73.0.3683.103
• OS version: Windows 10
• xterm.js version: 3.12.0

Steps to reproduce

1. Create code such as:

console.log(term._core.buffer.x);
term.write(longstring);
console.log(term._core.buffer.x);

4. Notice X has not been updated.

This is because parsing incoming data is fired asynchronously by design. Note that anything inside _core is private and you're not meant to be using. You will probably want #1994 when it gets in, in the meantime listen to .on('cursormove') to detect when changes to the buffer occur.
