/**
 * Calculates the Islamic prayer times for a given date and geographical location.
 *
 * This function computes the prayer times for Fajr, Dhuhr, Asr, Maghrib, and Isha,
 * as well as additional information such as sunrise, midnight, and the day length.
 * It also calculates the next prayer time based on the current date.
 * The calculation is influenced by the provided coordinates (latitude and longitude),
 * and optional settings for conventions (e.g., calculation methods) and Asr prayer calculation
 * (using the Hanafi method).
 *
 * @param date - The date for which the prayer times should be calculated. It must be a valid Date object.
 * @param coordinates - The geographical coordinates (longitude and latitude) of the location.
 * @param options - Optional settings that may influence the calculation methods, such as:
 *   - `convention`: Specifies the convention for Fajr and Isha calculation.
 *   - `hanafiAsr`: If true, the Hanafi method for Asr prayer calculation will be used.
 *
 * @returns An object containing the prayer times (`prayers`), additional information (`extras`), and any errors encountered:
 *   - `data`: An object with `prayers` (formatted prayer times) and `extras` (sunrise, midnight, day length, and next prayer).
 *   - `error`: An error object if calculation fails, or null if no error occurred.
 *
 * @throws {Error} If the input date is invalid, coordinates are out of range, or the location is in an unsupported polar region.
