[liusheng]

When try to build other projects depend on protolock on ARM64 server, it will raise error:

OS not supported. Unable to find a protolock binary for the classifier linux-aarch_64

This change add a protolock binary for ARM64/aarch64 platform.

Hi @rmichela ,
Could you please help to take a look this PR ? Thank you.

Where did you get the binary for arm64? There is no official protolock binary for that platform.

Sorry, I compiled the protolock binary on my ARM64 server, maybe need to firstly promote ARM64 release in protolock upstream ?

Yes. That's a good idea. 😄 While I like the idea of this PR, I can't accept an opaque binary that could do literally anything. Thank you for being understanding.

Hi @rmichela , Thanks for your reply and suggestion, I have promoted protolock upstream to published a new 1.15.1 version including ARM64 binary, see: https://github.com/nilslice/protolock/releases/tag/v0.15.1
I will update this PR replace with the new arm64 binary, please take a look again.
Thank you.
