This library has following Art-Net controller options.
Please use them depending on the situation.
- ArtnetSender
- ArtnetReveiver

- Artnet (Integrated Sender/Receiver)
### Warning
**From v0.1.11, arguments of callbacks must be `const` for safety. Previous sketches can not be compiled as is, so please add `const` to the arguments of callbacks.**

## Other Settings
### Net, Sub-Net, Universe, and Universe(15bit)
You can set Net, Sub-Net, Universe and Universe(15bit) flexibly.
### Subscribing Callbacks with Net, Sub-Net and Universe as you like
#### Sender
- You can set Net (0-127) and Sub-Net (0-15) like `artnet.begin(net, subnet)`
- Universe (0-15) can be set in `artnet.subscribe(universe, callback)`,
- Callbacks are limited to 4 universes (depending on the spec of Art-Net)
```C++
// set separately
artent.net(n);
artent.subnet(s);
artent.universe(u);
artnet.set(data, size);
// set as 15bit universe
artent.universe15bit(u);
artnet.set(data, size);
// set with data and size
artnet.set(universe15bit, data, size);
artnet.set(net, subnet, universe, data, size);
artnet.begin(net, subnet); // net and subnet can be set only once
artnet.subscribe(univ1, callback1); // 4 callbacks can be set
artnet.subscribe(univ2, callback2); // these universes are reported to
artnet.subscribe(univ3, callback3); // Art-Net controller if it polls
artnet.subscribe(univ4, callback4); // Art-Net devices
```
#### Receiver
### Sending Art-Net to Net, Sub-Net and Universe as you like
#### One-line sender
```C++
artnet.subscribe(universe15bit, function);
artnet.subscribe(net, subnet, universe, function);
artnet.send(ip, univ15bit, data, size); // use 15bit universer or
artnet.send(ip, net, subnet, univ, data, size); // net, subnet, and universe
```
### One Time Sending (Not Streaming)
In Sender class, you can also send Art-Net packet once.
This sends only 1 packet (NOT streaming).
#### Streaming
```C++
artnet.send(data, size);
artnet.send(universe15bit, data, size);
artnet.send(net, subnet, universe, data, size);
artnet.streaming_data(data, size); // set data first
artnet.streaming(ip, univ15bit); // stream to 15bit universe or
artnet.streaming(ip, net, subnet, univ); // net, subnet, and universe
```
### Set Non-Default Port
```C++
// ArtnetSender
artnet.begin(ip); // default
artnet.begin(ip, port); // set your own
// ArtnetReceiver
artnet.begin(); // default
artnet.begin(port); // set your own
// Artnet (integrated)
artnet.begin(ip); // default send/receiver
artnet.begin(ip, send_port, recv_port); // set your own
```
### ArtPollReply Setting
- This library supports `ArtPoll` and `ArtPollReply`
- `ArtPoll` is automatically parsed and sends `ArtPollReply`
- `net_sw` `sub_sw` `sw_in` etc. are set automatically based on registerd callbacks
- You can configure the information of `ArtPollReply` as follows
- `void shortname(const String& sn)`
- `void longname(const String& ln)`
- `void nodereport(const String& nr)`
