[Request] Align unaligned sequences to a profile

[Thernn88]

Would you consider adding an align to profile mode which will insert unaligned sequences into an existing alignment. Basically, akin to mafft's --add or --addfragments mode.

Currently, I can jank this through the profile-profile alignment by passing a single sequence as the second alignment. However, this is cumbersome and adds a layer of complexity.

Also if possible, could you add an option that maintains sequence order? I didn't see any option in help.

Thanks for this wonderful program!
