一代 pronounced as かずよ？


I saw the following example sentence on [WaniKani](https://www.wanikani.com):

あそこに立っている外人の男の人のとなりにいる女の人があのゆう名なまつい一代さんです。

_The lady next to the foreign guy standing over there is THE famous Kazuyo
Matsui._

The part I'm confused about is the name at the end: まつい一代さんです。

From what I've learned I would pronounce 一代 as ichidai (lifetime). I've not
ever seen either 一 or 代 pronounced in this way (kazuyo) before.

If there's not some other trick going on, how is かずよ divided among the two
kanji?
