Add Azimuth, Charge, and Elevation to RHS Rocket artillery

[grimsurgent]

Is your enhancement related to a problem?
With the ACE Compats, most RHS artillery such as the M109 and 2S3 gets AZ, CH, and ELEV added so players can use them effectively if the computer is disabled. The BM-21 and the HIMARS don't have these, which makes them unusable with the ACE artillery table.

Solution you'd like:
Azimuth, Charge, and Elevation added to the RHS rocket artillery (BM-21 and HIMARS)

Alternatives you've considered:
Right now, they can only effectively be used by AI if computer is disabled.

Additional context:
2S3 with Azimuth, Charge, and Elevation

BM-21 without it

IIRC the bm-21 is ported from arma2 and has some weird configs or memory points on how it works
I had to have some special code for the cup version:

ACE3/addons/artillerytables/functions/fnc_turretChanged.sqf

Lines 46 to 49 in 06336b8

	// If the memory point is invalid, then the turret will always use real weapon dir (e.g. CUP BM21)
	private _memoryPointGunnerOptics = getText (_turretCfg >> "memoryPointGunnerOptics");
	private _invalidGunnerMem = (_vehicle selectionPosition [_memoryPointGunnerOptics, "Memory"]) isEqualTo [0,0,0];
	if (_invalidGunnerMem) then { INFO_3("[%1-%2] turret's memoryPointGunnerOptics invalid [%3]",typeOf _vehicle,_turret,_memoryPointGunnerOptics); };

I'll try to track down what is different in the rhs version

Because we aren't in the GUNNER view (it's INTERNAL), it doesn't show the UI:

ACE3/addons/artillerytables/functions/fnc_turretPFEH.sqf

Lines 33 to 35 in e5178fe

	if (cameraView != "GUNNER") exitWith { // need to be in gunner mode, so we can check where the optics are aiming at
	_ctrlGroup ctrlShow false;
	};

The difference between the RHS and CUP BM-21 is that the CUP variant has a gunner view (it's worth nothing, but it exists), whereas the RHS version has nothing.
