Improve CRS selector component

[subashtiwari1010]

To work on the UI/UX of CRS selector to extend it's own functionalities.

Requirements

• Review UI of the CRS selector button
  • display the current CRS
  • allow to select a different CRS based on a list of preconfigured projection (as we are doing now)
  • [TBD] Usually the list of preconfigured CRS is not long so the filter is not actually needed. We could decide to remove it or make the text inside the button searchable
• A new settings button with cog icon will allow to open a dialog and select the projections usable in map based on the list of available projections. The dialog should allow a user to:
  • visualize a list of available projection with label and authority id
  • filter the list with text search
  • select the current map projection
  • select the projection usable inside the current map with a checkbox
  • on projection mouse over show the world extent on a map
  • persist applied changes in map configuration
• Review CRS selector configuration. We should simplify it, now we have a combination of filterAllowedCRS with additionalCRS to configure the default available CRS from localConfig.json. A single configuration should allow user to list all the default available configuration
• We may decide to allow also not allowed user to see the current selected projection without allowing interaction with it

Mockup

• New CRS button shows the current selected projection

• The quick selection will be allowed for the usable projection in map

• [TBD] Filtering system directly integrated inside the selected CRS. This is probably not actually needed

• The new dialog allow to navigate and select usable projections from the available ones

• On mouse over the projection world extent will be previewed on a small map

• Users to edit or change the current projection will be still able to see the current projection of the map if the plugin is configured
