Support for `arm`?

Hey @oldmoe,

I was going to give tinybits a try to replace a MessagePack implementation but ran into the following on my Mac Studio:

Fetching tinybits-0.6.0.gem
Building native extensions. This could take a while...
ERROR:  Error installing tinybits:

Is there any plans to have tibybits to support arm?
