Developer Notes when copying this system:
This system is developed by EmeraldLockdown, however no
credit is needed if your using it in your mod because it's simple.

HOW TO USE:
First, create your packet types (seen above these comments)
It should be pretty straight forward, you just set a packet
type for..... well.... different type of packets

To create a packet, use the create packet function.
Example:
`local p = create_packet(PACKET_TYPE_DESYNCED, network_global_index_from_local(0))`

In this example we set the packet type to PACKET_TYPE_DESYNCED,
and set the data to our global index

To send a packet to the server, you can use the
send_packet_to_server function, here's an example
using our previously made packet

`send_packet_to_server(p)`

Now we sent a packet to the server.... but what if we want to send a packet
to someone else? Well you can do this pretty easily by using the
send_packet function. Here's an example:

`send_packet(network_global_index_from_local(2), p)`

Now that player will recieve the packet, note that the send_packet
function uses the global index, not local.
