Glance at proposal about API change in pygwalker 0.4.8

[ObservedObserver]

In pygwalker 0.4.8, we are going to make some changes about pygwalker API, make it more semantic and accuracy.

General APIs

1. dark -> appearance
   Appearance is a more accurate and common used word it, the value is still choosen from 'dark' | 'light' | 'meadia'

pygwalker.walk(dark='media')

pygwalker.walk(appearance='media')

2. dataset -> data

Streamlit APIs

We changed some of the Imperative style parameter into more declarative style of API, since streamlit is a declarative UI framework.

1. StreamlitRenderer.render_expore() -> StreamlitRenderer.explorer()
2. StreamlitRenderer.render_filter_renderer() -> StreamlitRenderer.viewer()
3. StreamlitRenderer.render_pure_chart() -> StreamlitRenderer.chart()

Data Connection APIs (WIP)

1. from pygwalker.data_parsers
