💡 [REQUEST] - Review the migration of the Ledger HW Wallet repo to the SDK

Summary

Review whether it makes sense to migrate this to the SDK https://github.com/dinn2018/hw-app-vet and do so if the answer is yes.

One important thing is that the above repo is hard to use, specifically:

    public async getAppConfiguration() {
        const response = await this.transport
            .send(
                0xE0,
                0x06,
                0x00,
                0x00,
                Buffer.alloc(0),
                [StatusCodes.OK]
            )
        return response.slice(0, 4)
    }

This returns config values in a single byte array if I remember correctly, eg:

• App version
• Are multi clauses enabled?
• Are contract calls enabled?

Might be nice to explicitly expose these functions

Also, when signing a very large TX with large clauses etc. (eg contract deployments), the signTranasction can take a really long time with no feedback. VeWorld handles this by passing a callback function to return % complete:
