Add ARM64 support

[mratsim]

Similar to #43

Travis now supports ARM64 in CI (https://travis-ci.com/mratsim/Synthesis/jobs/267288652#L55), I usually use choosenim to manage my CI runs but unfortunately that would prevent me from using it for CI on ARM.

Please support arm architecture. raspberry pi nano, armv6

And also Apple Silicone chip (M1) (macosx_arm)

I've just bought a Macbook Pro M1 and disappointed to see this error when installing choosenim:

$ curl https://nim-lang.org/choosenim/init.sh -sSf | sh

choosenim-init: Error: Sorry, your platform (macosx_arm) is not supported by choosenim.
choosenim-init: Error: You will need to install Nim using an alternative method.
choosenim-init: Error: See the following link for more info: https://nim-lang.org/install.html

Hope to see Apple M1 support soon.

@p0w1nd see #283 (comment). Support should be fairly easy by just modifying the bash script. If you can help I would appreciate it :)

FYI, this is breaking on all ARM targets; including Raspbian and Armbian.

Bumping this. Nim nightlies are being pre-build for ARM64 (and also ARM7L).

@dom96 running a linux vm on Apple Silicone chip (m1/m2) is actually aarch64 or linux_arm64.

# uname -m      
aarch64

Running choosenim will end up with this error:
choosenim-init: Error: Sorry, your platform (linux_arm64) is not supported by choosenim.

anyway, both are the same and seem to be unsupported. is there any workaround/fix for this?
