fix: support for the latest version of ledger

[zakir-code]

The code in this branch is only used to resolve issues where ledger cannot sign transactions, so do not use it to run pundix nodes

Build from source

git clone -b zakir/ledger https://github.com/pundix/pundix.git
cd pundix
make build
./build/bin/pundix help
