pyiceberg-core: create even smaller artifacts (#1844)
## Which issue does this PR close?
- Closes #1839
## What changes are included in this PR?
use `lto = "thin", opt-level = "z"`
Tested building the wheel locally on mac. And this is the winning
combination.
Change | Wheel Size | Build Time | Notes
------------------------|------------|------------|------------------
fat LTO, opt-level=3 (default) | 21 MB | ~3 min | Original
fat LTO, opt-level=z | 12 MB | ~3 min | 43% smaller
thin LTO, opt-level=z | 12 MB | ~1.5 min | Same size, 2x faster build!
no LTO, opt-level=z | 13 MB | ~1 min | Slightly bigger
### Size Reduction
