geomap opt includes initial position

[OutOfBedlam]

This pull request focuses on refactoring the way initial map bounds and view settings are applied in the GeoMap module and its related test files. The changes involve using an opt object to store initialization parameters for better organization and maintainability.

Key changes include:

Refactoring map initialization:

• mods/codec/internal/geomap/geomap.go: Modified the Close method to use opt.initBounds and opt.initPoint for setting map bounds and view.

Updates in test files:

• mods/codec/internal/geomap/test/geomap_polygon.html: Updated to use opt.initPoint for setting the initial map view.
• mods/codec/internal/geomap/test/geomap_test.html: Changed to use opt.initBounds for fitting map bounds.
• mods/codec/internal/geomap/test/geomap_test_geojson.html: Refactored to use opt.initBounds for fitting map bounds.
• mods/tql/test/js-geojson-point.js: Updated to use opt.initPoint for setting the initial map view.
