`lambda_attributes` is a non-optional dependency for `lambda`

[stanislav-tkach]

According to the lambda Cargo.toml file, lambda-attributes is an optional dependency:

[features]
default = ["simulated", "derive"]
derive = ["lambda-attributes"]

[dependencies]
lambda-attributes = { path = "../lambda-attributes", version = "0.1.0", optional = true}

But in the lambda/lib.rs file lambda-attributes is used unconditionally:

pub use lambda_attributes::lambda;

Therefore it is impossible to use lambda with default-features = false.

I think this has been covered in #259 already.
