New document from SVG not supported

[Downchuck]

SVG Read-in support does not appear to be working.

In PyMuPDF, this works fine:

doc = pymupdf.Document(stream=bytearray(svg_str, "utf-8"))

In MuPDF.js, it fails:

doc = mupdf.Document.openDocument(new TextEncoder().encode(svg), "svg");

Error: cannot find document handler for file type: 'svg'

doc = mupdf.Document.openDocument(new TextEncoder().encode(svg));

const doc = mupdf.Document.openDocument("./please.svg");

Error: cannot find document handler for file type: './please.svg'
