Create mock synchronizer to help with driving the UI.
...
After experiencing several issues that make it more difficult to test send behavior, including the amount of time required to wait for blocks to get mined when testnet is slow,
it became obvious that it was time to investigate mocking. Most of the behavior in the SDK is driven by channels so the mock only has to focus on putting useful data in the
expected channels at the right time. One tradeoff here was the need to make all the synchronizer properties private, that way any implementation can achieve compatability
without necessasily leveraging the same combinations of building blocks. This tradeoff felt acceptable given that these dependencies can be injected and available as singletons,
if needed. This also had a side effect of elevating several channels into the Synchronizer interface, rather than reaching into the synchronizer to directly access those dependencies.
Another benefit is that it's now easier to see what matters most to the app, particularly which channels are essential.

Iterate and refine send and active transaction behavior
...
Send is now functional and shows up in active transactions.
This involved:
- reducing the exposure of the seed
- consistently using Ints for blockheight everywhere to match zcash
- adding the use of spending keys
- adding account initialization on startup
- using accounts but defaulting to account 0
- internalizing birthday so we no longer need a reference outside of the library
- enabling cancellation during send
- cleanup active transaction manager

Create ActiveTransactionManager to monitor active transactions

Create CompactBlockProcessor and refine responsibilities of collaborators
...
The synchronizer now primarily collaborates with a downloader, processor and repository; each with a more focused set of responsibilities.
The downloader streams blocks into a channel, the processor saves blocks from that channel and scans for transactions, the repository
exposes transaction change events.

Improvements to JniConverter.scanBlocks()
...
- Store Sapling tree with blocks
- Store witnesses with full notes
- Track note spends
- Track change notes
- Store index within block for each transaction
- This will make it easier to request entire blocks of transactions at
some point, and then filter out only the transactions we care about.
- Store block times while scanning blocks
- Return bool with error state from JniConverter.scanBlocks()
- Support cached blocks that are height-ascending but not sequential
- Blocks that do not contain Sapling data may be skipped.
- Return error from scan_cached_blocks() if heights are not ascending
