Add pointer to msg_sender in Eth_plugin_finalize (#170)

Browse Source 
* Add some PRINTF debug statements and fir additional screens init

* Memzero struture and use two pointers less

* Clang-format

* Use ADDRESS_LENGTH where possible; Add printf statements when failing to compare contracts

* clang-format

* Remove 'token1' and 'token2' locals

* Fix typo

* apply clang-format

* Add bip32path to sharedRO for plugins

* Change getEthAddressStringFromKey to accept char instead of uint8_t

* Update ethereum plugin sdk

* Add BYPASS_SIGNATURES compilation option

* Remove bip32path and pathLength from sharedRO; add msg_sender pointer to pluginFinalize.address

* clang format eth_plugin_interface

* Update submodule

* Set address BEFORE making the finalize call

* Update SDK
