Can't use a package with bit array segment on JS even if it is only used within the Erlang target

[brettkolodny]

Reproducible Code:

import gleam/io
import gleam/bit_array
import gleam/crypto

pub fn main() {
  io.debug(sign_message)
}

@external(javascript, "./ffi.mjs", "signMessage")
fn sign_message() -> String {
  let message = bit_array.from_string("foo")
  let key = bit_array.from_string("bar")

  crypto.sign_message(message, key, crypto.Sha256)
}

Output:

$ gleam check --target=js
error: Unsupported feature for compilation target
   ┌─ reproduce_error/build/packages/gleam_crypto/src/gleam/crypto.gleam:48:10
   │
48 │     <<x, left:bits>>, <<y, right:bits>> -> {
   │          ^^^^^^^^^

This bit array segment option in patterns is not supported for JavaScript compilation.
