Integrating AbortController support

[Antonio Musolino]

It can be cool to integrate the AbortController in the TCP environment. See options. We can try a POC in a PR.

Use example:

const controller = new AbortController();
const signal = controller.signal;

new Dats({..., signal })
.
.
.


process.on('exit', () => {
 controller.abort()
});

This is a Node 16 feature; we cannot add it until we support Node 12 and 14.
