[New Feature] Multiple Voxel Turrets

[nucspl]

Multiple features and settings expanding on the game's voxel turret definitions.
This is only a general idea, this doesn't necessarily cover everything, but it should be most of it.

Filenames to be read:
*tur/1, 2, 3... .vxl
*bar/1, 2, 3... .vxl
Should always read the numberless one first, so *tur is counted as 1, *tur1 is 2, and so on.

Rules Config:

; Turret-specific ROT
; Defines a specific turret's ROT, otherwise defaults to vanilla values.
[VOXEL_UNIT]
TurretXXROT=[integer]

Art Config:

MultiTurret

[VOXEL_UNIT]
MultiTurret=yes ; enables MultiTurret settings, otherwise defaults to vanilla turret settings
MultiTurretCount=[integer]

; MultiTurret FLH? Might not be necessary.
TurretXXFLH=F,L,H

; MultiTurret Offset, this is important, could also be expanded to have X-axis turret offset support in the future.
TurretXXOffset=[integer]

; MultiTurret Weapon Selection
; Different weapons per turret, otherwise defaults to both Primary and Secondary weapons cycling between all turrets.
PrimaryTurrets=[integer]
SecondaryTurrets=[integer]

If both Primary and Secondary are assigned a common turret, that turret will turn when either weapon assigned acquires an eligible target like in vanilla.

In this example, Turrets 3 and 4 share both weapons and will turn accordingly.

PrimaryTurrets=1,3,4,5
SecondaryTurrets=2,3,4

Turret Facing Settings

[VOXEL_UNIT]
; Turret Facing
; Defines the standby position/direction of the turrets, defaults to =Front
; Could also be an integer of 0 to 360 for specific angle directions.
TurretXXFacing=[Front, Back, Right, Left] or [positive integer of 0 to 360]

; Option to make the Turret keep its last firing angle as the standby direction, defaults to =no
TurretXXFacingKeep=[yes/no]

; Turret Fire Limitations
; Defines which facing the turret can't fire at, defaults to =none
; Could also be an integer of 0 to 360, covering a sector of a circle.
TurretXXFireLimit=[Front, Back, Right, Left] or [positive integer of 0 to 360]

Firing Styles:
Essentially how the turrets assigned under Primary/Secondary fire, firing from the first turret onward, last turret to first, or all at the same time.
This one's just an idea for later down the line once all the main parts have been implemented.
