ENH: Add ARM64 build assets for native functionality on M1 macs (the future)

[corneliusroemer]

It would be great if you could add OSX ARM 64 build targets for functionality with mac OSes future

Thanks!

As far as I can see, the D programming language doesn't have any compiler for ARM64 yet, so providing builds would be an impossible task:

dlang/dmd#16554

LDC and GDC both have supported ARM for quite a while, but DMD doesn't support it yet

I stand corrected, I indeed managed to compile tsv-utils with LDC on arm64 :)

$ make DCOMPILER=ldc2 DFLAGS='-linker lld'
