'On' event support for Serial / USB adapters

[ChronSyn]

Firstly, thank you for the fantastic library! Having TS built as standard into the library without relying on an external [at]Types definition is wonderful.

Onto the main issue. With node-serialport and node-usb, both support 'on' events, such as 'on data', 'on error', etc. These are usually handled as callbacks - e.g. serialport.on("data", (data: any) => callback(data)) - which triggers each time the serialport device sends data.

At present, this library doesn't provide such functionality. I have tried to implement such functionality myself, but I believe I may be implementing it incorrectly into the library.

One such use case for this is retrieving printer status (usually returned as a stream of bytes of n length). By sending certain thermal printers certain bytes (e.g. 0x10, 0x14, 0x07, 0x01), the device will respond with a stream of bytes (e.g. 0x14, 0x00, 0x00, 0x0f) which can be interpreted as multiple possible statuses such as 'ready', or 'cutter error', or 'paper being fed', etc, or a combination of statuses. The bytes to be sent and the bytes returned vary from printer to printer, so the ability to write bytes, and receive a callback when data is sent from the device would be highly beneficial.

Is it possible for such functionality to be added into this library?
