[aur-general] Request Delete and Merge

[BxS]

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.
