FUNCTION fHtmCoverCircleXyz

Returns HTM cover for a circle given with cartesian vector (x,y,z), radius

Returns a table of HTMID ranges covering a circle centered at CARTESIAN @x,@y,@z within @radius arcminutes of that centerpoint
@x float, @y float, @z float, cartesian unit vector for point
@radius float, radius in arcmins
Returns trixel table(HtmIDStart bigint, HtmIDEnd bigint)
