DateRangeHLSStream no data error

[ridswnt10]

Edge case to handle no data when given time range is not available in data files

[ayushmall0710]

The get_next_clip() method in the DateRangeHLSStream class lacks handling for the following edge cases:

• segment_start_index > num_total_segments : Occurs when the calculated start index exceeds the total number of segments in the current folder, leading to undefined behavior.
• No Next Folder: When transitioning to the next folder, the code assumes a next folder exists. If the current folder is the last one, this results in an index out-of-range error.

Proposed Solution:

• Add a check for segment_start_index > num_total_segments to skip the folder or end the stream if no data is available.
• Add a failsafe for missing the next folder by checking current_folder_index + 1 >= len(valid_folders) and gracefully ending the stream.

Impact Scope:

1. hls-utils: Improve robustness of get_next_clip() by handling edge cases.
2. ambient-noise-analysis: How is the data scenario handled here?
3. orca-action-workflow: Handle the no-data scenario here.

This seems to mostly be a problem with orca-hls-utils. @ayushmall0710 thanks for your detailed explanation, I moved your summary into a new issue in the orca-hls-utils repo: orcasound/orca-hls-utils#21
