Update Satochip plugin hardware wallet to support latest firmware v0.11

This allows to support the latest Satochip firmware v0.11 with improved performances and support for secure channel (encrypted and authenticated communication between the EC wallet and the card for improved security).
The plugin has been simplified by using the pysatochip library for communication with the card. Also, the Satochip_2FA plugin (used for optional 2-Factor-Authentication) has been merged with the Satochip plugin.
Seed generation: use BIP39 by default for better compatibility (instead of electrum seeds)
User interface improvements: 2FA can be activated from the option menu
