v2.1.0 (and v2.1.1) Update!

Just released a new update with a bunch of new features and fixes!

Oh... and another one with a very minor fix. I blame GameMaker for this one though.

v2.1.1 (25/05/2021):

• Added a workaround for an issue that seems like a GameMaker bug.

v2.1.0 (25/05/2021):

• Added "timer_destroy_object".
• Added "timer_set_paused_object".
• Added "timer_set_multiplier_object".
• Made it so that the timers now freeze when the instance they are assigned to is deactivated.
• Updated the example to showcase how the timers now work properly with deactivated instances.
• Fixed an issue with the "wait" function where it wouldn't work properly.
• Made changes to the documentation and the comments.
