Re-create meta.json in model directory, even if it exists. Especially
useful when updating existing spaCy models or training with Prodigy.
Ensures user won't end up with multiple "en_core_web_sm" models, and
offers easy way to change the model's name and settings without having
to edit the meta.json file.
Complain if no "lang", "name" or "version" is found (those settings are
used in directory / package names). Package will still build without,
but it'll inevitably fail somewhere down the line.
Add meta option to supply path to meta.json. If no meta path is set,
check if meta.json exists in input directory and use it. Otherwise,
prompt for details on the command line.
