simple_logger v1.12.0 fails to build with chrono feature and default_features = false

[amoskvin]

The new version fails with this combination of features. It worked with v1.11.0.

$ cat Cargo.toml
[package]
name = "sltest"
version = "0.1.0"
edition = "2018"

[dependencies.simple_logger]
version = "1"
default_features = false
features = ["chrono"]

$ cargo +stable build
   Compiling simple_logger v1.12.0
