update to zig master 0.10.0 and gyro v0.7.0

[voigt]

This is the result of issue #20 - Make this repo build again

The goal of this PR is to

• Make this repo build with the latest version of zig (master)
• update dependency management via gyro to 0.7.0
• decouple CI commands, so they can be used better for local testing
• add a daily schedule to run tests every day (on nightly master)

Unfortunately, I struggled to make windows work as described here.

Test	Linux	MacOS	Windows
simple	✅	✅	❌
gcd	✅	✅	❌
linking	✅	✅	❌
memory	✅	✅	❌
interrupt	✅	✅	❌

Any help fixing the windows build highly appreciated :)

Apologies for the very late response, but we're currently working hard to get Zig 0.10.0 ready for release.
The error in the CI for Windows unfortunately only points to the build runner. To get the full stack trace of the error, you'd have to run the actual executable. Once I have some extra time, I'll try running it through Wine to see what goes wrong.

Thanks for the response.
Sure, take your time - if the outcome is zig v0.10.0, I'm happy to wait :D
