/**
 * Merges custom RPC options with defaults. Returns a new instance and keeps
 * the "defaults" and the "options" unmodified.
 *
 * Merges `RpcMetadata` "meta", overwriting values from "defaults" with
 * values from "options". Does not append values to existing entries.
 *
 * Merges "jsonOptions", including "jsonOptions.typeRegistry", by creating
 * a new array that contains types from "options.jsonOptions.typeRegistry"
 * first, then types from "defaults.jsonOptions.typeRegistry".
 *
 * Merges "binaryOptions".
 *
 * Merges "interceptors" by creating a new array that contains interceptors
 * from "defaults" first, then interceptors from "options".
 *
 * Works with objects that extend `RpcOptions`, but only if the added
 * properties are of type Date, primitive like string, boolean, or Array
 * of primitives. If you have other property types, you have to merge them
 * yourself.
