/**
 * Creates a PathPaymentStrictReceive operation.
 *
 * A `PathPaymentStrictReceive` operation sends the specified amount to the
 * destination account. It credits the destination with `destAmount` of
 * `destAsset`, while debiting at most `sendMax` of `sendAsset` from the source.
 * The transfer optionally occurs through a path. XLM payments create the
 * destination account if it does not exist.
 *
 * @function
 * @alias Operation.pathPaymentStrictReceive
 * @see https://developers.stellar.org/docs/start/list-of-operations/#path-payment-strict-receive
 *
 * @param {object}  opts - Options object
 * @param {Asset}   opts.sendAsset    - asset to pay with
 * @param {string}  opts.sendMax      - maximum amount of sendAsset to send
 * @param {string}  opts.destination  - destination account to send to
 * @param {Asset}   opts.destAsset    - asset the destination will receive
 * @param {string}  opts.destAmount   - amount the destination receives
 * @param {Asset[]} opts.path         - array of Asset objects to use as the path
 *
 * @param {string}  [opts.source]     - The source account for the payment.
 *     Defaults to the transaction's source account.
 *
 * @returns {xdr.PathPaymentStrictReceiveOp} the resulting path payment op
