/**
 * # Azimuthal Equidistant Projection
 *
 * **Classification**: Azimuthal
 *
 * **Available forms**: Forward and inverse, spherical and ellipsoidal
 *
 * **Defined area**: Global
 *
 * **Alias**: `aeqd`
 *
 * **Domain**: 2D
 *
 * **Input type**: Geodetic coordinates
 *
 * **Output type**: Projected coordinates
 *
 * ## Projection String
 * ```
 * +proj=aeqd
 * ```
 *
 * ## Required Parameters
 * None
 *
 * ## Optional Parameters
 * - `guam`: Use Guam ellipsoidal formulas (accurate near Guam: λ ≈ 144.5°, φ ≈ 13.5°)
 * - `lat0`: Latitude of origin
 * - `lon0`: Longitude of origin
 * - `x0`: False easting
 * - `y0`: False northing
 * - `ellps`: Ellipsoid name
 * - `R`: Radius of sphere
