[JS] Remove unnecessary production dependencies

[jschaf]

Describe the enhancement requested

The Apache Arrow JS bundle includes a few unnecessary packages that increase the dependency graph. The culprits are:

• command-line-usage: used by integration.ts, json-to-arrow.ts, and arrowtocsv.ts. I think these can move to dev dependencies since it looks like the intent of the scripts is integration testing and benchmarking.
• @swc/helpers: Introduced in GH-37657: [JS] Run bin scripts with ts-node arrow#38500. @swc/helpers is never imported. I think it's used for https://github.com/apache/arrow/blob/9b931af14e5a710cba0aaa6b899e2ca696bfd785/js/tsconfig.json#L22. If ts-node is only for development, this can move to devDependencies.
• @types/node: Should move to devDependencies. I don't think there's any benefit to having it listed as a production dependency.
• @types/command-line-args: move to devDependencies
• @types/command-line-usage: move to devDepdencies
• json-bignum: used by integration.ts, json-to-arrow.ts, and arrowtocsv.ts. Can move to dev dependencies.

Here's the graph of the current dependencies.

arrow2csv is a bin provided by the library so we need to keep it as a dependency. We could probably remove that script, though but that's for another day. I removed swc in apache/arrow#41274. The types should be in the dependencies so people get the right versions.

The types should be in the dependencies so people get the right versions.

I think we only need to export types transitively used by exported libraries, not exported binaries. Since @types/command-line-args, and @types/command-line-usage are only used for the arrow2csv command and integration tests, they can probably live in dev dependencies.

Similarly, I suspect @node/types is only used for binaries and integration tests, but that's harder to verify.

We could probably remove that script, though but that's for another day

Alternately, publish as a separate package. Doesn't look like moving or deleting the file would break too much (usages).

[domoritz]

Good point. I'll update the pull request.

arrow2csv is a bin script for library consumers to use, e.g. curl /my/cool/api | npx arrow2csv | less

[domoritz]

Yeah, let's not remove it for now, that's a separate issue.

One could argue that cli tools should be separate packages and that js isn't the ideal language for cli tools (which is why I made https://github.com/domoritz/arrow-tools/tree/main/crates/csv2arrow ;-)).
