Callback doesn't work because can't read data

Hey, what the idea behind this pull request? https://github.com/zmeyc/telegram-bot-swift/pull/30/commits/b442d6763b437ee9a825425aaebcc494233c0bd0

Because of it example stop working https://github.com/zmeyc/telegram-bot-swift/blob/master/Examples/shopster-bot/Sources/shopster-bot/Controllers/MainController.swift

  // "toggle 1234567"
        guard context.args.scanWord() == "toggle" else { return false }
        guard let itemId = context.args.scanInt64() else { return false }

args is empty and always no reaction on inline keyboard press

Hi! Initially, if text was missing args were initialized with callback_query.data as a fallback. This allowed to use router for callback_data:

router["someCallbackData"] = { }

But this approach had two problems:

• router treats args as an abbreviation. For example, if "a" is sent as callback_query.data, it could trigger totally unrelated router["about"] command.
• user could simulate callback_query.data by sending it as plain text to the bot.

So, we removed the fallback. Now this form should be used instead:

router[.callback_query(data: "someCallbackData")] = { }

args should be replaced with context.update.callback_query?.data

I forgot to fix the example, thanks!
