Hibernate-Vector module enhancements

Support for binary, float16 and sparse vectors were added.

public class MyEntity {
	@Id
	UUID id;
	@JdbcTypeCode(SqlTypes.VECTOR_BINARY)
	@Array(length = 24) // Refers to the bit count
	byte[] binaryVector;
	@JdbcTypeCode(SqlTypes.VECTOR_FLOAT16)
	@Array(length = 3)
	float[] float16Vector;
	@Array(length = 3)
	SparseFloatVector sparseFloat32Vector;
}

The Hibernate Vector module currently ships with 3 sparse vector types:
