Let the user delete emails without confirmation

[lyz-code]

First of all thanks for developing himalaya and himalaya-vim.

I'd like to be able to delete the emails without confirmation, would it be possible to set a configuration option for that?

thanks!

This is definitely doable. A similar issue is opened for the CLI, see pimalaya/himalaya#469. Ideally, the Vim plugin should get this information from the CLI config.
