This PR is for adding new public APIs, and respective changes, to allow creating markers and adding marker events through API, instead through blocks.

What was happening

• When trying to add many markers into the map (> 500), the map became very slow
• What caused a decrease in performance was the extra html created by the blocks

What was done

• Added the code required to create new APIs in OutSystems to enable the creation of markers without blocks
• Additionally added the code required to add the events to markers via API, as well

Checklist

• tested locally
• documented the code
• clean all warnings and errors of eslint
• requires changes in OutSystems (if so, provide a module with changes)
• requires new sample page in OutSystems (if so, provide a module with changes)
