1.16.5 - 1.21.10

- Added new command `yov rem` to decrease variables:
Example: `yov rem test_haizenfell 1`
[YOV] Variable 'test' set to '-1'
[YOV] Variable 'test' decreased by 1. New value: -1

- Added rounding support:
%yov_player_key:test% == 14.543 → %rounded_player_key:test% == 15
%yov_player_key:test% == 14.443 → %rounded_player_key:test% == 14
Rounding always goes up.

- Added fractional rounding options:
%yov_player_key:test% == 14.543
%rounded_player_key_1:test% == 14.5
%rounded_player_key_2:test% == 14.54
and so on.

- Improved command filtering: now invalid options are automatically ignored.
