Discuss the need to add several common data types

[flymysql]

1. Embedding

The embedding type is often used in machine learning. Let me briefly mention the type requirement of embedding

1. It should support integer and floa types
2. It should be multi-dimensional

eg.

// float embedding
[1.1, 2.2, 3.3, 4.4]

// 2D floating point array
[[1.1, 2.2], [3.3, 4.4]]

// high dimensional array
[[[1.1], ...]]

Binary

Requires a data type that supports storing binary data
