* [#509] Remove OkHttp and Okio dependencies
- Okio -> Java NIO anf OkHttp -> HttpURLConnection in SaplingParamTool class
- Both replaced also in the test packages
- Removed dependencies to the replaced components
- Again switched a few assertions from JUnit to kotlin.test
- Created readLinesInFlow() function which is now reused in few places and runs without OkHttp
- Added subsequent TODOs to code base
- Wrapped to withContext to move it to an IO thread.
- Added use function on the stream and close() at the end of the channels use.

UnifiedViewingKey had a bug that made it incompatible with ZIP 316.
For compatibility with the current `zcash/librustzcash` revision we use
a temporary fake UFVK encoding that stores sufficient information to use
the current APIs, and a superset of the actual ZIP 316 FVK information.
While there are a lot of changes, the most significant are:
- Update the main entrypoint of the SDK to use a suspending function and eliminate lazy initialization. This also resolves#310
- Changing Dao methods to `suspend`, allowing Room to implicitly manage the threading model under the hood
- Explicitly set the executor thread for the `CompactBlockDb` and `DerivedDataDb`, which is the same thread used when calling into the Rust native library. Room will then use this thread for `suspend` fun calls into it
- With the above set, remove unnecessary hops to Dispatchers.IO which is a thread pool
- Eliminate lazy initialization in `PagedTransactionRepository` to make it easier to reason about the threading model and resolve#355 where the database was being touched from the UI thread
Note that `PendingTransactionsDb` is not opted into this single-threaded approach, because that database is not shared with the Rust code
Move SDK from the root gradle project to its own Gradle module
Move the demo app to be a peer of the SDK
This will simplify integration with CI on Bitrise.
