Support multiple layer in Kepler.gl view node

[koettert]

As a user I want to add several layers to the Kepler.gl view node. This could be achieved by supporting dynamic input tables whereas each input table is represented as its own layer in Kepler.gl

use dynamic input tables to include more tables
it also allow table without geo column, e,g., table with x and y column
