tls support is broken

[ghost]

Trying from the LTS version of Node.js, looks like the TLS connection is broken

$ node example/bitcoin.js
Connecting....

And the process is auto killed without any error logs

I assume that the library is broken, or have incompatible behavior with modern nodejs version

( I think this is the reason why ci fails as well )

Also, this comment is wrong

https://github.com/keep-network/electrum-client-js/blob/main/test/config.js#L18

I have tried with my electrum desktop client, and the server was working well.

So, I assume that the documentation of node.js is quite wrong with new tls.TLSSocket since many people use tls.connect instead.

Reverting the PR #10 fixed the issue.
