Work with Mirror Node team to read the archive files created for #1006

### Goal

After creating block archive files from all existing record files, we need to verify that the mirror node can import the data without error.

### Intention

Repeat the following for each archive file created under issue #1006.
- Read a single archive from cloud storage
- extract block files
- Uncompress a single block file using ZStd decompression
- Create an input stage in the Mirror Node import to unpack the block file to retrieve the original record file, sidecar file(s), and signature files.
- Verify that the existing mirror node import process can consume the data extracted from the "Block" file.

Start with the archive files created under issue #1006 and the existing Mirror Node import process. For each archive, follow the stated read, extraction, ZStd decompression, and input-stage steps. Done means the Mirror Node consumes the extracted block data without error and retrieves the original record, sidecar, and signature files.
