 * Request Permissions implementation to be used in JsonRpcEngine middleware, specifically for `wallet_requestPermissions` RPC method.

 * @param _next - JsonRpcEngine next() callback - unused
 * @param end - JsonRpcEngine end() callback
 * @param options - Method hooks passed to the method implementation
 * @param options.getAccounts - A hook that returns the permitted eth accounts for the origin sorted by lastSelected.
 * @param options.getCaip25PermissionFromLegacyPermissionsForOrigin - A hook that returns a CAIP-25 permission from a legacy `eth_accounts` and `endowment:permitted-chains` permission.
 * @param options.requestPermissionsForOrigin - A hook that requests CAIP-25 permissions for the origin.
 * @returns Nothing.
