FB_EQ2HOR - eps already in radians

Minor bug in STELLA1/STELLA1Runtime/POUs/FunctionBlocks/FB_EQ2HOR.TcPOU:

line 109:` last := lmst + d_psi *COS(eps*d2r)/3600.0 ; //add correction in degrees`

should be:` last := lmst + d_psi *COS(eps)/3600.0 ; //add correction in degrees`
eps is already in radians from FB_CO_NUTATE

accuracy increases by 0.5 to 1 arcsec.
Issue not present in FB_HOR2EQ.
