[aur-general] Request Delete and Merge

Hi, This is a cleanup on "C Compiler for PIC24 MCUs and dsPIC DSCs" packages in aur. Please delete [1]hitech-dspicc-bin, it's only needed for really old code. Please merge [2]microchip-mplabc30_bin into [3]microchip-mplabxc16-bin, c30 was replaced by XC16, I keep it for compability and because XC16 is too new, but since C30 don't like to work anymore with arch glibc is better simple move on to XC16. Thanks, keep the good work. [1] https://aur.archlinux.org/packages.php?ID=54315 [2] https://aur.archlinux.org/packages.php?ID=52725 [3] https://aur.archlinux.org/packages.php?ID=59174
