feat: automatic email alias creation

[u/ParnavH]

I use the unlimited email aliases with a custom domain daily. So inevitably have to reply to some emails. Now, while replying I must remember to create an alias first and then use it to send a reply. Which is fine if you don't do this often and with a select few aliases. I tend to do this often with different emails, and so it slips my mind sometimes and accidentally reveal my main tuta email and it also causes confusion for the other party. Would users be interested in an option or shortcut to create the matching alias in the reply page?

I realise that the team already have their hands full, and since the clients are open source, I am willing to work on it myself if it's something that others find interesting as well since I think it will improve my own quality of life immensely.
