Support continuous mode. #28

Closed caternuson closed 5 years ago

Fix for #26

Puts the wait for conversion loop in a conditional so it doesn't get used when running in continuous mode.

BEFORE (gets stuck in loop)

Oops. Looks like I accidentally deleted / closed this doing some house keeping? Not sure. Wasn't intentional. I guess if anyone actually still wants this, respond here and I'll see if I can bring it back.

OK. It's back. :)
