Replace secp256k1 crate with libsecp256k1. (#1029)

Browse Source 
* Replace `secp256k1` crate with `libsecp256k1`.

Unfortunately we could not implement `AsRef<[u8]>` for `SecretKey`
as the crate does not provide a means to do so.

* Fix `DecodingError` invocation.

* Remove the cc for wasm

* Revert "Remove the cc for wasm"

This reverts commit 3a19db35e62931c6e9ffbff6c21f9b0d7ae5403a.

* Fix CircleCI build
