Communication library between Rust and Ledger Nano S/X devices

# How to use

## Developing an App interface

To develop an app interface it's recommended to depend on `ledger-transport` and make the API generic over the an `Exchange` (trait).

An example can be found in [`ledger-zondax-hid` tests](./ledger-zondax-hid/src/lib.rs#L380) (provided by `ledger-zondax-generic`) where `get_device_info` is independent of the transport used.

## Using an App interface

To use an app interface, so when communicating with a ledger device (or emulator) the transports available are:

    * `ledger-transport-hid`

    * `ledger-transport-zemu`

# How to publish to crates.io

Obviously only members of the Zondax/crates team are allowed to publish.

Afterwards, there's a correct order to publish the crates, based on the crate dependencies:

* ledger-apdu

* ledger-transport

* ledger-zondax-generic

Then, the rest of the crates can be published in any order.

``sh

cargo login

cargo package -p ledger-apdu

cargo publish -p ledger-apdu

cargo package -p ledger-transport

cargo publish -p ledger-transport

cargo package -p ledger-zondax-generic

cargo publish -p ledger-zondax-generic

cargo package -p ledger-transport-hid

cargo publish -p ledger-transport-hid
