Added cancel charge method

[SlayerAnsh]

This pull request targets on adding Cancel Charge feature.

Important use case:

1. Cancel a charge before the default timeout
2. In some manual integration, to disable user from completing payment, canceling charge can be used.

Changes:

1. Added cancel crud method
2. Added cancel test

Note: Verification with actual api call is left. If someone can verify it, it would be really helpful.

wrote this small function that does the trick, let me know

import fetch from "node-fetch";

const cancelCharge = async (chargeCode: string, apiKey: string): Promise<void> => {
  try {
    await fetch(
      `https://api.commerce.coinbase.com/charges/${chargeCode}/cancel`,
      {
        method: "POST",
        headers: {
          "X-CC-Api-Key": apiKey,
          "X-CC-Version": "2018-03-22",
        },
      }
    );
  } catch (error) {
    console.log("cancelCharge error:", error);
  }
};

Yes, this works. I am using same using node-fetch in express backend. You can remove X-CC-Api-Key header as it is not required. (It should be required though)
