Additions 🎉

• Added CesiumUrlTemplateRasterOverlay, allowing a raster overlay to be added using tiles requested based on a specified URL template.
• Added EstimateTimeZoneForLongitude method to ACesiumSunSky to set a reasonable TimeZone value at the given longitude.
• The "Place Georeference Origin Here" button on ACesiumGeoreference will now adjust the time zone of the ACesiumSunSky instances that reference it, based on the new origin's longitude. This improves user experience when moving the origin to locations where it would be nighttime in the current time zone.
• Added RequestHeaders property to Cesium3DTileset, allowing per-tileset headers to be specified.
• Added RequestHeaders properties to CesiumTileMapServiceRasterOverlay, CesiumUrlTemplateRasterOverlay, CesiumWebMapServiceRasterOverlay,
  and CesiumWebMapTileServiceRasterOverlay, allowing per-raster-overlay HTTP headers to be specified.

Fixes 🔧

• Fixed another bug in CesiumSubLevelSwitcherComponent that could prevent all sub-levels from loading if a single sub-level failed to load.
• Fixed a crash in UCesiumIonServer when running in a packaged build where tilesets are only created at runtime.
• Worked around a limitation in Unreal's FMatrix -> FTransform conversion that prevented models with a small scale factor (e.g., where vertex positions are expressed in millimeters) from rendering because their scale was treated as 0.0.
• Fixed a crash when calling SampleHeightMostDetailed blueprint function without a valid tileset.
• Removed duplicate "Enable Water Mask" checkbox on Cesium3DTileset resulting from EditCondition flag.

In addition to the above, this release updates cesium-native from v0.43.0 to v0.44.0. See the changelog for a complete list of changes in cesium-native.
