 *
 * @param {string} asset A string of a supported asset in which to find the
 *     current price.
 * @param {string} [inAsset] A string of a supported asset in which to express
 *     the `asset` parameter's price. This defaults to USD.
 *
 * @returns {string} Returns a string of the numeric value of the asset.
 *
 * @example
 * ```
 * const rifi = new Rifi(window.ethereum);
 * let price;
 *
 * (async function () {
 *
 *   price = await rifi.getPrice(Rifi.WBTC);
 *   console.log('WBTC in USD', price); // 6 decimals, see Open Price Feed docs
 *
 *   price = await rifi.getPrice(Rifi.BAT, Rifi.USDC); // supports rTokens too
 *   console.log('BAT in USDC', price);
 *
 * })().catch(console.error);
