regexml-ucd-blocks-0.1.1 is not a library.
                    
                regexml-ucd-blocks
This contains a binary that produces (on standard output) a Rust module, using
the Blocks.txt, which is taken from the Unicode Consortium's UCD.zip.
If you have an updated Blocks.txt you can check it in here, and then update
the block.rs module in regexml as follows (in the project root):
cargo run -p regexml-ucd-blocks > regexml/src/block.rs
It would be better if icu_properties contains this information so that they are
up to date. I asked about this here:
https://github.com/unicode-org/icu4x/discussions/4798
I also considered the unicode_blocks module but it doesn't allow iteration
through the blocks which is what I require to do the name-based lookup.
