High Digit SAMs SA-20A/SA-20B Tin Shield Not Supported

[Whiskey-11]

With 2.0 of HDSM, Auranis added the ability to use the Tin Shield search radar to the SA-20A/SA-20B (both the "SA-5" Tin Shield and the new 40B6M Mast mounted Tin Shield from the DCS 2.9 S-300), however Skynet doesn't presently support it.

The following code needs to be added to the S-300PMU1 and S-300PMU2 search radars:

		['S-300PS 40B6MD sr_19J6'] = {
            ['name'] = {
                ['NATO'] = 'Tin Shield',
            },
        },
		['RLS_19J6'] = {
            ['name'] = {
                ['NATO'] = 'Tin Shield',
            },
		},	

That should add the Tin Shields as an acceptable search radar.
