[Bug]: html-minifier-terser stuck on empty file

[MalerasMek-Mikael-Lovqvist]

What happened?

If you run html-minifier-terser on an empty file it hangs. I realize that empty input files is not a normal situation but I don't think it should hang there, just produce an empty outfile.

To reproduce

This will hang forever

$ touch some-file.html 
$ html-minifier-terser some-file.html -o /dev/stdout

Caution

Make sure you don't already have content in the test file from testing the working case.

This will work

$ echo hello > some-file.html
$ html-minifier-terser some-file.html -o /dev/stdout
