Add "selectedDate" props to display selected date

[jserranojunior]

Feature

Add "selectedDate" props to display selected date If "startDate" is earlier than "selectedDate", it enables the option to navigate between these dates without disabling.

Example of use:

<VueTailwindPicker :start-date="startDate" :selected-date="selectedDate" @change="(v) => selectedDate = v"

data(){ return:{ startDate: "2020-01-01", selectedDate: "2020-05-01", } }

I'm working on it to make a commit
