fix(types): change speaker and related fields from float to int

[lukeocodes]

Summary

Fixes #641

Changed speaker, channel, and num_words fields from float to int in Listen V1 response types to match the actual API response format.

Issue

In SDK v5, the speaker field was incorrectly defined as float, causing subtitle generation tools like deepgram-captions to display speakers as "speaker 0.0", "speaker 1.0" instead of "speaker 0", "speaker 1". This is a regression from SDK v4.8.

Changes

Modified the following type definition files:

1. listen_v1response_results_utterances_item.py - Changed speaker and channel from float to int
2. listen_v1response_results_utterances_item_words_item.py - Changed speaker from float to int
3. listen_v1response_results_channels_item_alternatives_item_paragraphs_paragraphs_item.py - Changed speaker and num_words from float to int

Test plan

• Verify that speaker IDs are now returned as integers (0, 1, 2) instead of floats (0.0, 1.0, 2.0)
• Test with deepgram-captions package to ensure subtitles display "speaker 0" format
• Ensure backward compatibility with existing code
