small fixes and improvements

- Minor improvements

- Minor improvements to the conditions for displaying the loot icon for killed NPCs.
- Added check for union 1.0m and above. The plugin will not work with older versions.
- Improved compatibility with zSavesBackuper.vdf

Added the ability to enable a mode in which only objects in the line of sight of the hero will be shown.

- Minor initialization refactoring.
- Added an alternative hidden mode of the plugin. In this mode, the plugin shows a panel with information about the number of items near the hero without the exact location of the item. Additionally, you can enable the display of the total number of items of this category in the location. By default, the new feature is disabled.
Attention: "Max" mode and the function of pulling items do not work in stealth mode.
