Bitcoin puzzle solver package

Make a package that makes it possible to coordinate the search of private key for Bitcoin address from Bitcoin Puzzle.

For example, `puzzle #66` if solved gives 6.6 bitcoin (almost 4 000 000 ₽) to the one who did it.

This task may be computationally expensive, so it should be solved using multiple CPU, possibly GPU, and done by multiple users, otherwise using single CPU the cost of worst case computation will be around 35 million years for 66-th puzzle.

```
ninja.wallets.singlewallet.generateNewAddressAndKey();
const url = 'https://www.blockchain.com/explorer/addresses/btc/' + document.querySelector('#btcaddress').innerText;
window.open(url, '_blank')
```

There is some small, but non-zero probability to generate private key for already existing bitcoin address with positive balance.
