Add override for gasPrice (to ethers-wallet) about ethers-meow HOT 1 OPEN

The gas price currently comes from the Ethereum network, but yes I should add the ability to override it for those wish to have finer grained control. Give me a day to think about the best way to support this in a more general way.

I think I will add a optional function to signers for getGasPrice(tx).

I would also like to add a feature where the gasPrice can be set to specific constants, in which case it will use the ethers gas oracle; for example "low" would use the current safe low value for the network. I still need to think more about this though, since it will greatly increase the traffic to my public API.

If you need something ASAP, for now, you can just create a custom signer, which will allow you to override this.

var ethers = require('ethers');
var meow = require('ethers-meow');

function CustomSigner(privateKey) {
    this.provider = ethers.providers.getDefaultProvider();

    var wallet = new ethers.Wallet(privateKey, this.provider);

    this.address = wallet.address;

    this.sendTransaction = function(tx) {
        tx.gasPrice = 25000000000;
        console.log(tx);
        return wallet.sendTransaction(tx);
    }
}

var customSigner = new CustomSigner('0x0123456789012345678901234567890123456789012345678901234567890123');

var manager = new meow.Manager(customSigner);

manager.giveBirth(1000);
