Shielded Support for Ledger Hardware Wallets (NanoS+, NanoX)

NanoS supports Transparent and Sapling.

I barely managed to make it fit. Less than 100 bytes of RAM left and that’s after manually optimizing the code size by looking at the generated assembly code…

We need testers! If you have a NanoS, or S+ and are proficient with using the command line, you can help by using YWallet 1.4.0 & Ledger.
