Pull request description:

  Fixes #1153
  Replaces #1194

  ### Description

  Introduce universal structures that represent sync/full-scan requests/results.

  ### Notes to the reviewers

  This is based on #1194 but is different in the following ways:
  * The functionality to print scan/sync progress is not reduced.
  * `SyncRequest` and `FullScanRequest` is simplified and fields are exposed for more flexibility.

  ### Changelog notice

  * Add universal structures for initiating/receiving sync/full-scan requests/results for spk-based syncing.
  * Updated `bdk_esplora` chain-source to make use of new universal sync/full-scan structures.
