Component | Plotband: Add plotband component

[50rayn]

In this PR will be added Plotband element in the chart. Since it's a common detail in other libraries, like Highcharts plotband, ECharts markArea etc., I implemented this idea in the current library.

In order for the example to be part of the website, you need to add an entry inexamples-list.tsx, and add a screenshot in the _previews folder.

@50rayn started the review, but halfway realized a lot of the things echo what Nikita left in the plotline component. Could you please do a round of update here first?

@50rayn build failed. Do you want to take a look?

Fixed. Missed some files in the examples, like dark preview and .ts file. Now the build is passing.
