Ensure web-stream is released after detection

[Borewit]

1. Resolves Chromium consistently crash after processing ~990 files (of several specific types) with fileTypeFromBlob - a.readFromStream WebStreamReader.js - TypeError: network error #678
2. Resolves fileTypeFromStream throws an error in combination with [email protected] #681

CI is failing

Release of strtok3 v9.0.1, will cause problems with file-type v19.5.0 (reason CI was failing). It exposes a the following issue:

file-type/index.js

Lines 13 to 17 in 0e91f7b

	try {
	return super.fromTokenizer(tokenizer);
	} finally {
	await tokenizer.close();
	}

where the tokenizer is closed after return the promise, and not after resolving the promise.

Raised bug: #681
