feat(proto): add archway-proto crate (#18)

Rust build of Archway's ProtoBuf definitions.

This package can be used both in CosmWasm smart contracts and gRPC
clients. It is based on the [`cosmos-sdk-proto
v0.18.0`](https://github.com/cosmos/cosmos-rust) crate to provide the
Cosmos SDK `v0.45.x` messages and follows the same feature definitions,
with the `tonic` gRPC clients enabled by default.

## Usage

### In CosmWasm smart contracts

```toml
archway-proto = { version = "0.1.0", default-features = false, features = ["cosmwasm"] }
```

### For the gRPC client functionality (won't work in CosmWasm)

```toml
archway-proto = "0.1.0"
```
