parquet: No method named `to_ne_bytes` found for struct `bloom_filter::Block` for target `s390x-unknown-linux-gnu`

Describe the bug

When publishing Python wheels on CI for the latest version of arro3-io, which uses the parquet crate, it no longer builds for parquet v56 on the s390x-unknown-linux-gnu target. (It built fine for parquet v55).

error[E0599]: no method named `to_ne_bytes` found for struct `bloom_filter::Block` in the current scope
   --> /root/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/parquet-56.0.0/src/bloom_filter/mod.rs:125:27

    | ------------ method `to_ne_bytes` not found for this struct

    |
    = help: items from traits can only be used if the trait is implemented and in scope
    = note: the following trait defines an item `to_ne_bytes`, perhaps you need to implement it:
            candidate #1: `num::traits::ToBytes`
help: there is a method `to_le_bytes` with a similar name
    |
125 -         self.swap_bytes().to_ne_bytes()
125 +         self.swap_bytes().to_le_bytes()

To Reproduce

I'm not exactly sure how to reproduce this outside of CI. On my mac, I can't reproduce for that target; it succeeds for cargo build -p parquet --target s390x-unknown-linux-gnu and fails for a different reason (with ring) when --all-features is passed.

Expected behavior

Should compile.

Additional context

I'm not sure if there are specific targets that are supported/unsupported? If s390x-unknown-linux-gnu is not supported, I can close this issue and just not build Python wheels for that target.

This sounds related to the performance optimizations that I did in #7824, let me take a look.
