append rizin results in plaintext to include tabs etc (fixes #3193) (#…

…3236)

the output of rizin was formatted as html, which caused \n to become
<br/>, making it impossible to just use appendPlainText() as-is. We have
to tell rizin not to give us html, so that we can use \t in the output.

Simply replacing \t with spaces, `&emsp;` or similar doesn't work, as
the appendHtml() replaces multiple spaces with one.
