Review comment:
I tried this and sadly I am told:
```shell
alamb@ip-10-0-0-124:~/Software/arrow-rs/arrow$ cargo build --target
wasm32-unknown-unknown
error: failed to parse manifest at
`/Users/alamb/Software/arrow-rs/arrow/Cargo.toml`
Caused by:
feature `getrandom/js` in dependency `rand` is not allowed to contain
slashes
If you want to enable features of a transitive dependency, the direct
dependency needs to re-export those features from the `[features]` table.
```
