Update Compel to 2.1.1 and apply Sentences Split logic

[hipsterusername]

Summary

This pull request introduces changes to improve text handling in the compel node and updates project metadata and dependencies in pyproject.toml. Key updates include enabling sentence-based splitting for long text prompts, updating dependency versions, and revising project metadata to reflect the current state of the project.

We should consider advising that very long prompts may have different results using the new parsing logic, but are reproducible if manually split using the .and() parsing logic.

Changes to text handling in compel.py:

• Added SplitLongTextMode.SENTENCES to the split_long_text_mode parameter in two instances of Compel initialization, enabling more graceful splitting of long text prompts. [1] [2]
• Imported SplitLongTextMode from the compel library to support the new functionality.

Updates to pyproject.toml:

• Updated the compel dependency version from 2.0.2 to 2.1.1 to ensure compatibility with the new text-splitting functionality.
• Revised project metadata

QA Instructions
