Add support for Telegram topics (telegram) (#1942)

Topics are surfaced by appending /<topic-id> to the channel setting for the gateway. 
An example for the topic with ID of 16 would be:

```
[[gateway.inout]]
account="telegram.mytelegram"
channel="-100xxxxxxxxxx/16"
```

-# Golang bindings for the Telegram Bot API
-
-[![Go Reference](https://pkg.go.dev/badge/github.com/go-telegram-bot-api/telegram-bot-api/v5.svg)](https://pkg.go.dev/github.com/go-telegram-bot-api/telegram-bot-api/v5)
-[![Test](https://github.com/go-telegram-bot-api/telegram-bot-api/actions/workflows/test.yml/badge.svg)](https://github.com/go-telegram-bot-api/telegram-bot-api/actions/workflows/test.yml)
-
-All methods are fairly self-explanatory, and reading the [godoc](https://pkg.go.dev/github.com/go-telegram-bot-api/telegram-bot-api/v5) page should
-explain everything. If something isn't clear, open an issue or submit
-a pull request.
-
-There are more tutorials and high-level information on the website, [go-telegram-bot-api.dev](https://go-telegram-bot-api.dev).
-
-The scope of this project is just to provide a wrapper around the API
-without any additional features. There are other projects for creating
-something with plugins and command handlers without having to design
-all that yourself.
-
-Join [the development group](https://telegram.me/go_telegram_bot_api) if
-you want to ask questions or discuss development.
-
-## Example
-
-First, ensure the library is installed and up to date by running
-`go get -u github.com/go-telegram-bot-api/telegram-bot-api/v5`.
-
-This is a very simple bot that just displays any gotten updates,
-then replies it to that chat.
-
-```go
-package main
-
-import (
-	"log"
-
-	tgbotapi "github.com/go-telegram-bot-api/telegram-bot-api/v5"
-)
-
-func main() {
-	bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
-	if err != nil {
-		log.Panic(err)
-	}
-
-	bot.Debug = true
-
-	log.Printf("Authorized on account %s", bot.Self.UserName)
-
-	u := tgbotapi.NewUpdate(0)
-	u.Timeout = 60
-
-	updates := bot.GetUpdatesChan(u)
-
-	for update := range updates {
-		if update.Message != nil { // If we got a message
-			log.Printf("[%s] %s", update.Message.From.UserName, update.Message.Text)
-
-			msg := tgbotapi.NewMessage(update.Message.Chat.ID, update.Message.Text)
-			msg.ReplyToMessageID = update.Message.MessageID
-
-			bot.Send(msg)
-		}
-	}
-}
-```
-
-If you need to use webhooks (if you wish to run on Google App Engine),
-you may use a slightly different method.
-
-```go
-package main
-
-import (
-	"log"
-	"net/http"
-
-	"github.com/go-telegram-bot-api/telegram-bot-api/v5"
-)
-
-func main() {
-	bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	bot.Debug = true
-
-	log.Printf("Authorized on account %s", bot.Self.UserName)
-
-	wh, _ := tgbotapi.NewWebhookWithCert("https://www.google.com:8443/"+bot.Token, "cert.pem")
-
-	_, err = bot.SetWebhook(wh)
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	info, err := bot.GetWebhookInfo()
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	if info.LastErrorDate != 0 {
-		log.Printf("Telegram callback failed: %s", info.LastErrorMessage)
-	}
-
-	updates := bot.ListenForWebhook("/" + bot.Token)
-	go http.ListenAndServeTLS("0.0.0.0:8443", "cert.pem", "key.pem", nil)
-
-	for update := range updates {
-		log.Printf("%+v\n", update)
-	}
-}
-```
-
-If you need, you may generate a self-signed certificate, as this requires
-HTTPS / TLS. The above example tells Telegram that this is your
-certificate and that it should be trusted, even though it is not
-properly signed.
-
-    openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3560 -subj "//O=Org\CN=Test" -nodes
-
-Now that [Let's Encrypt](https://letsencrypt.org) is available,
-you may wish to generate your free TLS certificate there.
