Initialize the ENet library. Must be called before using any ENet functionality.

Deinitialize the ENet library, cleaning up all resources. Call this when you no longer
need any ENet functionality.

Create an ENet host for either a client-like unbound host or a server bound to a specific
address and port:
- If no argument is provided, creates an unbound "client-like" host with default settings
(maximum 32 peers, 2 channels, unlimited bandwidth).
- If you pass an "ip:port" string (e.g. "127.0.0.1:7777"), it creates a server bound to
that address. The server supports up to 32 peers, 2 channels, and unlimited bandwidth.
Throws an error if host creation fails for any reason.
:param address: (optional) A string in 'ip:port' format to bind the host (server), or
omit to create an unbound client-like host.
:return: An ENetHost object.

Poll for and process any available network events (connect, receive, disconnect, or none)
from this host, calling the provided callback for each event. This function loops until
no more events are available in the current timeframe.
Event object properties:
- type: String, one of "connect", "receive", "disconnect", or "none".
- peer: (present if type = "connect") The ENetPeer object for the new connection.
- channelID: (present if type = "receive") The channel on which the data was received.
- data: (present if type = "receive") The received data as a *plain JavaScript object*.
If the JSON parse fails or the data isn't an object, a JavaScript error is thrown.
:param callback: A function called once for each available event, receiving an event
object as its single argument.
:param timeout: (optional) Timeout in milliseconds. Defaults to 0 (non-blocking).
:return: None

Initiate a connection from this host to a remote server. Throws an error if the
connection cannot be started.

Broadcast a JavaScript object to all connected peers on channel 0. The object is

Configure the throttling behavior for this peer, controlling how ENet adjusts its sending
