⚡️ Speed up function get_likely_indent_size by 7%

[codeflash-ai]

📄 7% (0.07x) speedup for get_likely_indent_size in evaluation/benchmarks/biocoder/scripts/setup/remove_code.py

⏱️ Runtime : 578 microseconds → 542 microseconds (best of 1429 runs)

📝 Explanation and details

Changes Made

1. Avoid Repeated Length Calculation: Calculated the length of array_of_tabs once and stored it in array_len.
2. Use zip for Iteration: Used zip to iterate through the array, shifting from indexing which avoids the need to access elements multiple times.
3. Simplified Empty Check: Used if not sizes to check if the dictionary is empty, which is more idiomatic and faster.
4. Direct Max Calculation on Dict Items: Used max directly on dictionary items, as it is inherently faster and clearer.
