Simple testnet deployer for Uniswap

Use it 🍩

``js
const Deployer = require('@blockchangers/uniswap-testnet-deployer').Deployer;
const deployer = new Deployer(WALLET)
const tokenExchanges = await deployer.setup()
`
or
`js
import { Deployer } from '@blockchangers/uniswap-testnet-deployer';
const deployer = new Deployer(WALLET)
const tokenExchanges = await deployer.setup()
`

Returns

async setup(tokens?: Token[]): Promise
`js
export type TokenExchange = {
tokenAddress: string,
exchangeAddress: string
}
`

Example JS setup 🤞

`js
const ethers = require('ethers');
const ganache = require('ganache-cli');
const UniswapTestnetDeployer = require('@blockchangers/uniswap-testnet-deployer');
const MNEMONIC = 'popular stock metal artefact nasty venture oblige horror face glory predict coach';

const provider = new ethers.providers.Web3Provider(
ganache.provider({
"mnemonic": MNEMONIC,
"gasLimit": 8000000,
"default_balance_ether": 100000000,
"verbose": true,
"vmErrorsOnRPCResponse": true
})
);

(async () => {
const WALLET = ethers.Wallet.fromMnemonic(MNEMONIC).connect(provider)
const ADDRESS = await WALLET.getAddress()

const deployer = new UniswapTestnetDeployer.Deployer(WALLET)
const tokenExchanges = await deployer.setup()
console.log("### First setup ###")
console.log(tokenExchanges)

// With custom tokens
const TOKENS = [
{
name: "MyToken",
symbol: "MYT",
amount: 50000,
depositAmount: 200,
valueInEther: 516
},
{
name: "Blockchanger TOKEN",
symbol: "BCT",
amount: 100000,
depositAmount: 5000,
valueInEther: 15
},
];
const tokenExchanges2 = await deployer.setup(TOKENS)
console.log("### Second setup ###")
console.log(tokenExchanges2)

const anExchange = new ethers.Contract(tokenExchanges2[0].exchangeAddress, UniswapTestnetDeployer.exchangeAbi, WALLET);
const anToken = new ethers.Contract(tokenExchanges2[0].tokenAddress, UniswapTestnetDeployer.tokenAbi, WALLET);
const oneEthToTokenPrice = await anExchange.getEthToTokenInputPrice(ethers.utils.parseEther("1"))
const symbol = await anToken.symbol()
console.log("1 ETH of", symbol, "equals", ethers.utils.formatEther(oneEthToTokenPrice.toString()))
})().catch(err => {
console.error(err);
})
`

Default tokens

`js
export const DEFAULT_TOKENS: Token[] = [
{
name: "MakerDAO",
symbol: "MKR",
amount: 50000,
depositAmount: 200,
valueInEther: 516
},
{
name: "Basic Attention Token",
