Tested locally against all versions of Node.js 18 or higher, and this works as expected. Thanks for the fix!
Extend the Node.js test matrix so Blob-related failures on modern runtimes are caught in CI, as discussed in Stuk#941. Signed-off-by: Jon Koops <jonkoops@gmail.com>

Resolves #941.
Node has
Blobbut notFileReader. Instead, we can convert a blob's contents to anArrayBufferusingBlob.prototype.arrayBuffer.This approach should stick pretty closely to what the code already does (transparently try to convert a
Blobto anArrayBufferbefore doing anything else to it).I've also fixed the test code so that it doesn't try to read certain properties of the passed blob unless it's actually a
Blob--if that particular test helper is called with an error, theblobargument will benull, and we'll get spurious errors that terminate the entire test suite early.
