Tagged values are used to store sparse values.

They consist of an array of RecordTag, each RecordTag has an Identifier and an offset to the start of its data. The length of the data in each record is determine by the start of the next record.

Example:

00000050 00 01 0c 40 a4 01 21 00 a5 01 23 00 01 6c 00 61 |...@..!...#..l.a| 00000060 00 62 00 5c 00 64 00 63 00 2d 00 31 00 24 00 00 |.b.\.d.c.-.1.$..| 00000070 00 3d 00 f9 00 |.=...|

Slice is 0x50-0x75 00010c40a4012100a5012300016c00610062005c00640063002d003100240000003d00f900 Consumed 0x15 bytes of TAGGED space from 0xc to 0x21 for tag 0x100 Consumed 0x2 bytes of TAGGED space from 0x21 to 0x23 for tag 0x1a4 Consumed 0x2 bytes of TAGGED space from 0x23 to 0x25 for tag 0x1a5

type Value

	PageID int64
	Flags  uint64

	BufferOffset int64

	// contains filtered or unexported fields
}

TODO: This is called LINE in the MS code. It represents a single node in the page. Depending on the page type it needs to be further parsed.
