Describe the issue

Hi, I recently migrate from old bootstrap3 datetimepicker to latest tempus dominus v6.
After a lot of migration code, all is working but i see that input set as readonly now can be still edited with tempus dominus ( with old datetimepicker, if a field got a readonly attribute, it can't be modified).
I know i can set "disabled" instead "readonly" to solve this issue, but you know during form submit, "disabled" inputs are not submitted....
So i prefer use "readonly" when i can..... any suggest to disable tempus dominus from firing calendar when input has a readonly? Thanks
