Replaces the bet function with one that provides authentic results at no cost.

// Example Usage: Pass the wager amount and target payout as you normally would however there's an additional
// but optional third parameter to specify a balance amount, if this is provided it will be appropriately
// adjusted with the resulting winnings/losses and returned within the result as expected.

let testBalance = this.balance;
let result = await this.bet(100, 2.9, testBalance);
this.log(JSON.stringify(result));
// {"id":0,"timestamp":"Sat May 09 2020","value":100,"target":2.9,"multiplier":9.07,"balance":1000190,"bankroll":null}


// If no balance is specified then the balance returned is the resulting winnings/losses for the roll
// (which can be recorded and then summed to calculate the net profit over the course of multiple bets.

let netProfit = 0;
let result = await this.bet(100, 2.9, netProfit);
this.log(JSON.stringify(result));

// {"id":0,"timestamp":"Sat May 09 2020","value":100,"target":2.9,"multiplier":1.16,"balance":-100,"bankroll":null}
