v0.3.0

Summary

• Samples are now sent individually rather than aggregated in the kernel, which in some cases it lead to stack quality issues. This will also allow to send per sample data such as timestamp and cpu core which will be used in future features
• Fixes on how the base address is calculated, improving unwinding success for other linkers and loaders
• Zig 🦎 is now fully supported (All the gory details in #264)
• Many other bug-fixes and smaller features
