Add persistence to components

Thanks for this great library. I enjoy the beautiful-styled controls and often use them in my projects. Lately I found out that Dash supports a convenient way to make user-data persistent by adding a persistence attribute. So a slider that keeps its data persistant now basically comes down to one line of code:

slider = dcc.Slider(id="slider_1", persistence=True, persistence_type="local")

This dramatically simplifies the cases where before one had to pass all user-values to a Store component. I would love to see this feature implemented in dash-daq components and also would be willing to contribute. What are your thoughts?

Is there a recommended build-system? I always get errors when using yarn start like described in the Readme. I tried it on Ubuntu and Mac OS with yarn 1.22.4 and npm 6.14.4.

Hey, how did you resolve this issue? I am trying to build the library and these two files generate the same error for me. I was able to run the yarn dash-demo command or demo.py as I changed the Slider to Slider.Slider and ColorPicker to ColorPicker.ColorPicker but is there something I am missing that will generate these two files as well?

Actually I think I wasn’t able to build it on my own computer so I had to rely on CI to do building for me. 🤔
