MacOS requires coreutils for sha256sum

[ironicbadger]

This entire issue is prefaced by acknowledging macos isn't a supported platform :)

Expected behaviour

Run quickget ubuntu 20.04 and have the sha256sum verify.

quickemu % ./quickget ubuntu 20.04
ubuntu-20.04/ubuntu-20.04.4 100%[=========================================>]   3.15G  12.5MB/s    in 3m 22s
Checking ubuntu-20.04/ubuntu-20.04.4-desktop-amd64.iso with sha256sum... ./quickget: line 577: sha256sum: command not found
ERROR!
ubuntu-20.04/ubuntu-20.04.4-desktop-amd64.iso doesn't match f92f7dca5bb6690e1af0052687ead49376281c7b64fbe4179cc44025965b7d1c. Try running 'quickget' again.

Actual behaviour

sha256sum not found. Requires installing coreutils, for example with brew install coreutils.
