Remove dead code from tyndall

Due to the updates in node_comm, the iterate and typevals utilities have been moved into libblunux and they've been also made macos/clang compatible. In addition to this, all zmq functionlity has been replaced with azmq so there is no need for the zmq_proto utility either.

 # Highlights
 
-## meta/iterate
-
-Function that calls the given callback with integral constants from 0 to the specified index.
-Useful for iterating at compile time.
-
-Example:
-```cpp
-#include <tyndall/meta/iterate.h>
-
-iterate<10>(
-[](auto index){
-  // index = std::integral_constant<int, 0>(), std::integral_constant<int, 1>(), ... ,std::integral_constant<int, 9>()
-  static_assert((index >= 0) && (index < 10));
-  printf("%d ", index()); // 0 1 2 3 4 5 6 7 8 9
-});
-```

 ## meta/strval
 
 compile time string which ensures "string A"\_strval and "string A"\_strval have the same type,

-## meta/typevals
-Container where entries can have different types.
-
-Example:
-```cpp
-#include <tyndall/meta/typevals.h>
-
-struct A{int a; float b;};
-struct B{double x; char y; char z;};
-
-static constexpr auto tv = typevals{} + 5 + A{4,2} + B{3,9,1};
-static_assert(tv.size() == 3);
-
-constexpr auto A42 = tv.get<1>();
-static_assert(A42.b == 2);
-constexpr auto B391 = tv[std::integral_constant<int, 2>()];
-static_assert(B391.x == 3);

-## zmq\_proto
-
-[ZeroMQ](https://zeromq.org/) ([libzmq](https://github.com/zeromq/libzmq)) / [Protobuf](https://developers.google.com/protocol-buffers) based tcp communication.
-
-Example:
-
-### Publisher
-```cpp
-#include <tyndall/proto/zmq_proto.h>
-
-zmq_proto::context_t context{1};
-zmq_proto::socket_t<zmq_proto::PUB> socket(context, "tcp://*:5444");

-msg.set_value(42);
-
-int rc = zmq_proto::send(msg, socket);
-if (rc != 0)
-  printf("errno: %s\n", strerror(errno));
-```
-
-### Subscriber
-```cpp
-#include <tyndall/proto/zmq_proto.h>
-
-zmq_proto::context_t context{1};
-zmq_proto::socket_t<zmq_proto::SUB> socket(context, "tcp://127.0.0.1:5444");
-
-while(1)
-{
-  google::protobuf::Int32Value msg;
-
-  int rc = zmq_proto::recv(msg, socket);
-  if (rc != 0)
-  {
-    printf("errno: %s\n", strerror(errno));
-    exit(1);
-  }
-}

 ## ros\_context
 A wrapper around ros.
 It provides a minimal of lazy methods for sending and receiving ros messages and service calls.
