Cargo Features

MILF has no features set by default.

[dependencies]
milf = { version = "0.5.8", features = ["preserve_order"] }
preserve_order = indexmap

Use indexmap rather than BTreeMap as the map type of milf::Value.
This allows data to be read into a Value and written back to a MILF string while preserving the order of map keys in the input.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
