Allow disabling options validation for production use.

[GuillaumeRochat]

While running the test repeatedly, I noticed that the time it takes to do a validation is quite high, around 2-5ms per check. With some debugging, I noticed that most of that time is from the runtime checks on the options and presets by yup.

Considering that the options and preset will be hardcoded, yup could be disabled in the production build to significantly cut on runtime. For example, the tests for the blank symbol ? take between 100ms and 200ms with yup enabled, but around 2ms with up disabled.
