Description
A serialized vamana ssd index needs to be readily deserialized by diskannpy. This is a tracker to add all additional serialized files that are needed to support this. The complete list of files is at https://github.com/microsoft/DiskANN/blob/a26f824be5a597b49a7bf33f51ee75121e7c03af/python/src/_static_disk_index.py#L51
- We must investigate if
{index_prefix}_sample_data.binand{index_prefix}_sample_ids.binis essential or optional - As mentioned in #905, the pq_pivots currently are to be supplied by the user
- For the remaining files, match the correct suffixes with expectations of diskannpy

Research direction
Start with the file list in diskannpy's python/src/_static_disk_index.py at the linked revision, then compare those suffix expectations with the serialized Vamana SSD index. Investigate whether {index_prefix}_sample_data.bin and {index_prefix}_sample_ids.bin are required, and account for the pq_pivots behavior noted in #905. Done means the remaining serialized files use suffixes that diskannpy can deserialize.
