CPU does not seem to support SSE2

[mooijtech]

Hello,

Thank you for this awesome library, I appreciate it a lot.
I intend to use it for generating IDs related to PST email messages (importing to ClickHouse).
I am getting the following panic on my Linux local machine and VPS:

panic: sno: CPU does not seem to support SSE2 instructions required on amd64 platforms

As you can see "flags" contains "sse2" which the library is complaining about.
I was wondering if you have any solution to this?

Thanks in advance,

@mooijtech @alcore did anybody figure this one out? I am having the same issue; however, if I simply run tests in sno's repository, everything works fine.

[yrashk]

I figured it out -- 1.1.0 does not contain fixes required for this to work. @alcore any chance you can release a new tagged version?

[alcore]

Apologies! This somehow ended up under my radar and I had a large hiatus -- correct, a tag push didn't make it upstream.

https://github.com/muyo/sno/tree/v1.2.0 is now tagged and released.

I'll leave this open for a while should anything else have slipped by my attention.
