Describe the bug

Loading empty index causes python runtime terminated.

Steps to reproduce

from pathlib import Path
from usearch.index import Index
import numpy as np

# ensure there is no file prior to test
index_path = Path('index.usearch')
if index_path.exists():
    index_path.unlink()

index = Index(ndim=3)
index.save(index_path)
index.reset()
assert index_path.exists()

# Here python interpreter just exits
# terminate called after throwing an instance of 'std::runtime_error'
# what():  Resource temporarily unavailable
try:
    index = Index.restore(str(index_path)) 
except Exception:
    pass

Expected behavior

Python runtime exits without errors. Or an exception is thrown that Python code could catch.
