TelnetSocket.setEncoding() causes 'data' listener to fail.

[jordan-tiona]

const server = new Telnet.TelnetServer( rawSocket => {
    const telnetSocket = new Telnet.TelnetSocket();
    telnetSocket.attach( rawSocket );
    telnetSocket.setEncoding( "utf8" );
} ).netServer;

The first time any data is received after this point there is a TypeError given:

C:\Projects\mud\node_modules\ranvier-telnet\index.js:154
      databuf.copy(inputbuf, inputlen);
              ^

TypeError: databuf.copy is not a function
    at Socket.<anonymous> (C:\Projects\mud\node_modules\ranvier-telnet\index.js:154:15)
    at Socket.emit (node:events:513:28)
    at addChunk (node:internal/streams/readable:324:12)
    at readableAddChunk (node:internal/streams/readable:293:11)
    at Readable.push (node:internal/streams/readable:234:10)
    at TCP.onStreamRead (node:internal/stream_base_commons:190:23)

It appears that the incoming data is not being checked for encoding:

connection.on('data', (databuf) => {
    databuf.copy(inputbuf, inputlen);
    inputlen += databuf.length;

My attempted fixes have proven ineffective. I will update if a solution is found.
