Only one link per pool

[0xB10C]

We don't need multiple links per pool. This just makes it harder to generate dataset for downstream tools.

I've used this python script for this patch:

#!/usr/bin/env python3

import json
import glob
import sys

entity_files = glob.glob("pools/*.json")

addresses = dict()
tags = dict()

for file_path in entity_files:
    with open(file_path, "r") as f:
        e = json.load(f)

        link = ""

        if len(e["links"]) == 0:
            print(f"No links for pool {e['name']}")
        elif len(e["links"]) == 1:
            link = e["links"][0]
        elif len(e["links"]) > 1:
            link = e["links"][0]
            print(f"Using {link} for pool {e['name']} out of", e["links"])

        content = {
            "name": e["name"],
            "addresses": sorted(e["addresses"]),
            "tags": sorted(e["tags"]),
            "link": link,
        }

        with open(file_path, "w") as out:
            json.dump(content, out, indent=2, ensure_ascii=False)
            out.write('\n')

It did output:

• bitarms.io -> bitfarms.io
• btc.canoepool.com -> canoepool.com
