Possible mistake in "type node48 struct "

[candrade2020]

In node.go, will be keys 48 bytes long?

type node48 struct {
	node
	children [node48Max]*artNode
	// keys     [node256Max]byte
	keys    [node48Max]byte
	present [4]uint64 // need 256 bits for keys
}

Please read spec for Node48 here: https://db.in.tum.de/~leis/papers/ART.pdf

Node48

...
a 256-element array is used, which can be indexed with key bytes directly. If a node has between 17 and 48 child pointers, this array stores indexes into a second array which contains up to 48 pointers.
