feat: new BlockReader implementation for block-as-file

[ata-nas]

Description:

• adding reading logic to complement feat: new BlockWriter implementation for block-as-file #281

Related issue(s):

Fixes #349

Notes for reviewer:

• what would be the best way to parse the block file, having a file input stream and calling readAllBytes does not seem like the best option, there are other (based on the api), but which one would be preferable?

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)
