Fix compatibility with variants of ElectrumX

[ghost]

There are currently five major electrum clients

1. ElectrumX maintained by Electrum Team

https://github.com/spesmilo/electrumx

2. ElectrumX maintained by Original Author which seems to drop support for every chain except Bitcoin SV

https://github.com/kyuupichan/electrumx

3. Electrs which is rewritten in Rust & have better connection management

https://github.com/romanz/electrs

4. Fullcrum which is rewritten in C++ & supports Bitcoin Cash

https://github.com/cculianu/Fulcrum

5. jelectrum which is rewritten in Java

https://github.com/fireduck64/jelectrum

Those five clients have slightly different API implementations and they require a different length of parameters ( And, some methods are missing as well like this issue I have created romanz/electrs#698 )

My idea is to detect which client is being used by calling version,

and call with different parameters by the client.

What is more, it turns out that Blockstream's electrs does not support verbose transactions Blockstream/electrs#36.

I've been working it around in keep-network/tbtc-v2#501.
