Not possible to disable `crypto_expressions` feature as a library user of DataFusion.

[phillipleblanc]

Describe the bug

Both the datafusion core crate and datafusion-functions crate have a default feature for crypto_expressions.

datafusion/core/Cargo.toml

crypto_expressions = ["datafusion-functions/crypto_expressions"]
default = [
    "array_expressions",
    "crypto_expressions",
...

datafusion/functions/Cargo.toml

crypto_expressions = ["md-5", "sha2", "blake2", "blake3"]
...
default = [
    "core_expressions",
...
    "crypto_expressions",
...

If I disable all features from DataFusion when importing the crate in my project, the crypto_expressions dependencies are still enabled because datafusion-functions enables them by default.

To Reproduce

cargo new --bin df_crypto
cd df_crypto
cargo add datafusion --no-default-features
cargo build
cat Cargo.lock | grep blake2

Expected behavior

Disabling default features from the core crate should not get re-enabled by default elsewhere.

Additional context

I will submit a PR to fix this.
