bump substrate to polkadot-v0.9.2. + add GA + re-add branch ids (#116)

* bump paritytech/substrate@1d7f6e1. Closes #117.
* re-introduce branch identifiers
* Add GitHub actions

#### Rationale Branch Ids:

Polkadot references substrate dependencies including `branch = "master"`. Hence, any rust crate that uses substrate AND Polkadot deps must use the branch-id because Cargo can't identify them as the same even if the same substrate revision is referenced.

This is the api-client branch that is currently used with the encointer-client.
