This PR fixes a data type compatibility issue in the GigaAM transducer encoder where the output length tensor could be either int32 or int64, but the code only handled int32. The fix adds runtime type checking and supports both data types.

- Adds runtime detection of encoder output length tensor data type (int32 vs int64)
- Implements conditional data access based on the detected type
- Adds error handling for unsupported data types

…har tokens instead of BPE. (#2423)

A new method and property were introduced in the VoiceActivityDetector C++ and Python APIs to 
provide access to the current speech segment as soon as speech is detected, rather than only 
after the segment completes.
