Rework sqlite: Instead of only supported one schema (defined in `bdk_sqlite`), we have a schema per changeset type for more flexiblity. * rm `bdk_sqlite` crate (as we don't need `bdk_sqlite::Store` anymore). * add `sqlite` feature on `bdk_chain` which adds methods on each changeset type for initializing tables, loading the changeset and writing. Rework changesets: Some callers may want to use `KeychainTxOutIndex` where `K` may change per descriptor on every run. So we only want to persist the last revealed indices by `DescriptorId` (which uniquely-ish identifies the descriptor). * rm `keychain_added` field from `keychain_txout`'s changeset. * Add `keychain_added` to `CombinedChangeSet` (which is renamed to `WalletChangeSet`). Rework persistence: add back some safety and convenience when persisting our types. Working with changeset directly (as we were doing before) can be cumbersome. * Intoduce `struct Persisted<T>` which wraps a type `T` which stores staged changes to it. This adds safety when creating and or loading `T` from db. * `struct Persisted<T>` methods, `create`, `load` and `persist`, are avaliable if `trait PersistWith<Db>` is implemented for `T`. `Db` represents the database connection and `PersistWith` should be implemented per database-type. * For async, we have `trait PersistedAsyncWith<Db>`. * `Wallet` has impls of `PersistedWith<rusqlite::Connection>`, `PersistedWith<rusqlite::Transaction>` and `PersistedWith<bdk_file_store::Store>` by default. Rework wallet-construction: Before, we had multiple methods for loading and creating with different input-counts so it would be unwieldly to add more parameters in the future. This also makes it difficult to impl `PersistWith` (which has a single method for `load` that takes in `PersistWith::LoadParams` and a single method for `create` that takes in `PersistWith::CreateParams`). * Introduce a builder pattern when constructing a `Wallet`. For loading from persistence or `ChangeSet`, we have `LoadParams`. For creating a new wallet, we have `CreateParams`.
