Bug: Concurrent queries over the same connection

[Aditya-ds-1806]

Steps to reproduce:

I Modified the example program to execute 2 queries simultaneously with the same client:

package main

import (
	"fmt"
	"sync"

	"github.com/dicedb/dicedb-go"
	"github.com/dicedb/dicedb-go/wire"
)

func main() {
	client, err := dicedb.NewClient("localhost", 7379)
	if err != nil {
		fmt.Println(err)
	}

	var wg sync.WaitGroup

	wg.Add(2)

	go func() {
		defer wg.Done()
		resp := client.Fire(&wire.Command{Cmd: "PING"})
		fmt.Println(resp)
	}()

	go func() {
		defer wg.Done()
		resp := client.Fire(&wire.Command{Cmd: "HANDSHAKE", Args: []string{"hsajdbsdbs", "command"}})
		fmt.Println(resp)
	}()

	wg.Wait()
}

If we try running this, after several tries we will notice one of the commands fail (PING in this case). Also, when there was no failure, response was sent for one command and after that the server just hanged, there was no response.

Thanks for raising this. Picking this up on priority.
