Failure on empty tags

[iskrenvankov]

Hi,
I ran into an issue recently using another library that is based on simple-html-tokenizer.
Here is a link to the original issue: nfrasser/linkifyjs#370

The particular minimal failure example I can provide is the following:

Example input: Foo/Bar <> Zoo/Zar

Expected output: same as the input (no change)

Observed output: Foo/Bar <zoo></zoo>
