[ENH] New Gallery

[acocac]

Feature Request

The current gallery chapter contains all notebooks indexed by theme with a drop-down list. This isn't the most attractive and accessible format for readers/users.

Describe the solution you'd like

@scotthosking has suggested a great idea to replace the drop-down list with a single section pointing to a gridded gallery similar to Pangeo Gallery or Scivision.

Describe alternatives you've considered

• Manually adding grids using Sphinx-design
• Automatically add items to the gallery with a YML. See JupyterBook Gallery
