Support step and format on DateSlider

[MarcSkovMadsen]

The current version of Panel is 0.12.1.

If I look at the Bokeh DateSlider I can see it supports a step and format which the Panel DateSlider does not.

I think supporting that would be quite useful for Panel as that would allow sliding through other timeperiods than days down to milliseconds as far as I can see.

Todo

It's probably as simple as

• Add step and format parameters to Panels DataSlider
• Add tests or test manually that it works
• Update reference guide.

Additional Context

It would for example increase the possibilities for Creating a dynamic map with datetime range. See #673

Hi, long time lurker but I guess I kinda want to get involved after using panel for more than a year now. How can I push my changes to a branch to make my first PR @MarcSkovMadsen ?
I also added the format option in the daterangeslider as requested in #2894

[Axeldnahcram]

I guess I need to fork my own version of panel. I will do it tonight
