* Don't use compressed ecdsa public key in verify

* Make `ECDSA` public support compressed

* Make it a proper `expect` message

Changes in https://github.com/paritytech/substrate/pull/4462 required a
metadata version increment that was forgotten.

* Make wasm-builder remove invalid members

Wasm-builder now removes members that point to packages that do not
exist anymore or that were renamed. Up to now, the build would fail and
required manual fixing.

* Fixes build

* Fix cli for structopt 0.3.7 and pin to that version

This is just some hotfix to make everything compile. In the future it
will require another pr to not depend on internals of StructOpt, but
that will probably also require some additions to StructOpt itself. To
not break the code again with another StructOpt, this also pins the
StructOpt version.
