feat: create item meta data & .pyz files

[hemanialaparthi]

This pull request introduces significant enhancements to the inventory system, including support for .pyz packages, new item creation functionality, and improvements to file validation and packaging.

.pyz Package Support

• Added functionality to handle .pyz files in the Acquisition class, including validation and transmission to the API. This ensures .pyz files are properly integrated into the inventory system (src/inventory/Acquire.py).
• Introduced the Packager module to create .pyz packages from item directories, with validation and staging logic to ensure package integrity (src/inventory/Packager.py).

Item Creation Enhancements

• added a new Create module to facilitate the creation of inventory items, including metadata, Python modules, and packaging options. This module supports both interactive and non-interactive modes (src/inventory/Create.py).
• updated pyproject.toml to include create and packager commands for item creation and packaging (pyproject.toml).

Validation and File Handling Improvements

• Enhanced the Instance class to validate file paths using absolute paths and improved error messaging during file validation (src/inventory/Instance.py).
• Updated the Acquisition class to compress binary files before transmitting them to the API, reducing payload size (src/inventory/Acquire.py).

Minor Changes

• Added missing imports and improved import organization across multiple files for consistency (src/inventory/Acquire.py, src/inventory/Use.py).
• Fixed formatting and removed unused imports in the Instance class (src/inventory/Instance.py).
