Add flag to toggle building executable (#81)

Some distributors need to use the old Cabal-v1 build systems, which will build the 'extensions' executable even if it isn't needed (for instance when this package is only needed as a dependency for stan). This adds a new 'executable' flag (enabled by default) which will allow for disabling the 'extensions' executable if it isn't needed.
