Feature request: add "block" subcommand

[DustinByfuglien]

It would be useful to add "block" subcommand to generate ranges from Blocks.txt - unicode blocks.

Patches welcome.

ucd-generate is a wonderful app. Thank you very much for it. It helps me to make own regex engine.

Sorry I know very few about github and ucd-generate internal sctructure and it's can take a time and some efforts to study it.
Please If it's trivial and don't take significant efforts for you then consider to add this feature.
If no I'll take a time to learn how all it works and may be can add this feature in future.

I'm not planning to work on this because I don't need it. ucd-generate is really meant to be a dumping ground for folks to push Unicode data generation into a common tool.

Please If it's trivial and don't take significant efforts for you then consider to add this feature.

It would probably be a few hours of work for me. But I don't have a few hours of time to spare. Sorry.

[DustinByfuglien]

Thanks.

There is the unicode-blocks crate which may fill that gap until blocks is added to this crate?
