Write coordinates along normal mode

[similt]

When we displace the system along a normal mode, how to write the new coordinates in POSCAR format?

@similt I suggest https://github.com/JMSkelton/ModeMap for that purpose.

Right, if you can produce input to ascii-phonons then presumably you already have a way of generating displaced structures! (Probably Phonopy...)
