Burst using multiple fire mechanics instead of automatic fire mechanics

Same scenario as #1475

The hero now uses this weapon to shot bursts:

And tries to shot a burst to each Deep One, but he cant since the system only allows to shot 2 bursts

The system is using the multiple shot mechanic for burst:

• max bursts: as defined by the multiple shots field at weapon sheet
• rolling: +1P for all bursts

But the ruling might be the one for automatic fire:

• max bursts: as the player decides, no max
• rolling: +1P cumulative for each burst after the first one

References:

Pg 113 KR - Handguns, Multiple Shots: Many handguns can fire 2 or 3 shots per round. Doing so requires a roll with a penalty die on each shot.
Pg 114 KR - Automatic Fire: There are 3 modes an automatic gun could be, depending on the gun: Full Auto, Burst Fire, and Semi-Automatic/Multiple Single Shots
Full Auto: player decides number of bullets to be fired in total, then divided into volleys with an attack roll per volley. Volleys are determined by the appropriate firearm skill divided by 10, rounded down, but never fewer than 3.
Burst Fire: One pull of the trigger is 2 or 3 bullets, depending on weapon. This is treated as a volley for the purposes of Automatic Fire.
Semi-Automatic: Same as the handgun version of Multiple Shots; each bullet fired needs a skill check made with a penalty die.

So burst fire functions the same as automatic fire, except volley/burst sizes are determined by the weapon rather than the skill of the character.
