【datasets】datasets for Euclidean distance and inner product distance

[frg01]

I would like to ask why there are no data sets of Euclidean distance and inner product distance types.

@frg01 We have conducted some tests and found that the dimension and size are the most important attributes of the dataset, while the metric_type has a relatively smaller impact on performance.

We will consider two directions in the future:

• Continuing to update more datasets to cover more scenarios.
• Supporting customizable datasets.

If you have any suggestions, feel free to share them with us.
