[WIP] Substrate Airgapped

Tools to facilitate an air-gapped construction, decoding, and signing flow for transactions of FRAME-based chains.

Crates

• substrate-airgapped-cli: CLI that combines all functionality of the available substrate-airgapped libraries.
• substrate-airgapped: Where core components & functionality is being built out.
• substrate-metadata: A wrapper around runtime metadata that can be used to programmatically get the call index of transaction.

Examples

• substrate-airgapped/examples/signed_tx_from_pair.rs: Construct a balance transfer, hard-coding the call index.
• substrate-airgapped/examples/call_index_from_metadata.rs: Dynamically get the call index from metadata.
