I don't understand.  I thought tree-sitter itself was such a parser.
Why do we need another one as an Emacs module?

Because the only implementation possible for emacs is the generic parser. It needs specific parsers to be inserted. The two are orthogonal, but related.

Emacs cannot and should not contain such parser binaries. They are os and architecture specific. 

Also, this way the parsers can more easily be fixed

Does that make sense?
