Add support for WARTHOG (WART)

[blackmennewstyle]

Commit c65b3ba officially adds support for WARTHOG (WART) 🔥 🚀

In order to work properly the following procedure details how to setup a WART node for pool mining.

The WARTHOG WIKI is full of wisdom. And knowledge is always what you seek as a mining pool operator. BEFORE even considering jumping into the WART network, make sure you fully master all the economics and mechanics behind it.

One of the many guides available in order to install, configure and understand how the node works: https://warthog.network/docs/guides/compiling/

A pool configuration for WARTHOG can be found inside the examples folder: https://github.com/blackmennewstyle/miningcore/blob/dev/examples/warthog_pool.json

Replace all the specific options with the correct expected values. It should be plug and play as long as everything is filled correctly.

WARNING: WARTHOG requires to enter your wallet private key inside the config.json using "walletPrivateKey": "<DANGER: The Warthog Node's wallet private key which owns the pool address>", in order to be able to send payments.
I did my best to never reveal that very sensitive piece of data in the API, so be very careful as well.
