* Adopt SDK 1.10.0 API changes
* Rename ShieldedSapling -> LegacySapling
* Viewing key re-derived for fix fixture value
* Changes used API for retrieving Transparent address
- Switched API DerivationTool.deriveTransparentAddress() -> Synchronizer.getLegacyTransparentAddress()
- Renamed Transparent -> LegacyTransparent
* Adds new common transaction model class
- Synchronizer.toTransactions() now works only with clearedTransactions and pendingTransactions
-Added CommonTransaction wrapper for all attributes of PendingTransaction and TransactionOverview to cover as much as possible. It's prepared for discussion about which attributes we really need and which we can omit.
* Regeneration of addresses in fixture
- Applies for both Transparent and Sapling addresses
- Fixed related test
- Added a new test for checking Transparent address abbreviation, as it also serves as a little check of the fixture address and can prevent an incorrect address change in the future
* Remove Viewing key usage from entire app
- As we agreed that the app should not access to it now
- Removed from all related places
* Change CommonTransaction to sealed class
* Comments update
* Switch SDK to 1.10.0-beta01-SNAPSHOT version
* Revert back legacy naming on Transparent and Sapling addresses
* Increased timeout limit to satisfy SDK initialization
