Lack of interest Generate files hash when importing templates for xenforo addon

[RisteDimitrievski]

I'd like to have cmd option to regenerate file hashes for original file that we've modified.

For example if i modify templates and run

xf-dev:export
xf-addon:import XF
// it will import data in `src/addons/xf/_data` but will not update `hashes.json`
