Remove max_addresses sync param

You can do this with ensure_addresses_cached if you really want to.

@@ -21,6 +21,7 @@ To decouple the `Wallet` from the `Blockchain` we've made major changes:
 - Changed `Wallet::sync` to take a `Blockchain`.
 - Stop making a request for the block height when calling `Wallet:new`.
 - Added `SyncOptions` to capture extra (future) arguments to `Wallet::sync`.
+- Removed `max_addresses` sync parameter which determined how many addresses to cache before syncing since this can just be done with `ensure_addreses_cached`.
