Add streaming features and missing pre recorded features

[DamienDeepgram]

Proposed changes

Add streaming features and support for pre-recorded features when streaming.

Note that this modifies some public enum's which are used internally but might need to be taken into account

• Bumped the minor version but it might need a major bump?

Types of changes

• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update or tests (if none of the other choices apply)

Checklist

Further comments

Also considered a different approach with a SerializeStreamingOptions and have the code still just in case but this followed existing patterns
