lambda_http isn't compatible with serde features = ["derive"]

[iliana]

Current documentation instructs users of Serde to use the derive feature in Cargo.toml:

serde = { version = "1.0", features = ["derive"] }

This is incompatible with lambda_http which uses separate serde and serde_derive crates.

error[E0252]: the name `Deserialize` is defined multiple times

error: Could not compile `lambda_http`.

If a user switches back to the old serde_derive crate, lambda_http successfully builds.

serde = "1.0"
serde_derive = "1.0"

Hi @iliana! Long time no see :)

This may be related to #97 I believe there's an incompatibility that may be fixed with a publish of lambda_http mentioned in #97 (comment)

This seems to be fixed with the most recent release (#103).
