Removes the 1s option from flashbangs

[1080pCat]

What Does This PR Do

You can no longer set the fuse timer on flashbangs to one second

Why It's Good For The Game

This is with 2(?) balance team members pre approval. (im unsure what the second member meant, but they seem fine with it?)

Flashbangs have started to become a quite cheesy method of closing the distance with people who lack one of the two forms of bang(ear) protection, and theres been a rather sharp increase of players treating others like a blob, and throwing upwards of 6 flashbangs on 1s timers, leading to no reaction time on the victim, removing the one second option should hopefully add a little skill requirement to 'insta flashing' as accurately timing 5/3 seconds with adrenaline in your system isn't the easiest thing todo.

not to mention if you lack eye protection the flashbang spam will likely blind you very quickly

this does not effect base grenades, only flashbangs the options it gets now are as follows 0.1seconds ('truly' instant, if a clown gets ahold of your flashbox, you're in for a surprise. and as the bang part of the flashbang also effects you even if you have ear pro i think its fine.) 3 seconds 5 seconds

Hopefully this discourages/adds more skill to using flashbangs, as you will need to actually count in your head if you wish to surprise people with a flashbang

~~also technically a blob buff~~

Testing

compiled, checked the flashbang options with a screwdriver
