Issue 2: Implementing Object Storage

[vk17-starlord]

Description:
Build the core object storage system to handle Git objects (blobs, trees, and commits). This issue focuses on storing and retrieving data in a content-addressable format.

Goal Commands:

• No user-facing commands yet; internal functions for object storage.

Tasks:

1. Create blob objects:
   • Read file contents.
   • Compress the content using zlib.
   • Generate a SHA-1 hash for the object.
   • Write the object to the appropriate path in objects/.
2. Implement functions to retrieve stored objects by their SHA-1 hash.

Expected Outcome:

• Blob objects can be created and retrieved from the objects/ directory.
