Contributor guide

Research direction
Read the linked issue #254 in rust prometheus to understand the desired IntHistogram interface. Study the existing histogram implementation and the local histogram (LocalHistogram) for inspiration. Implement the struct and methods for IntHistogram, ensuring it mirrors the Histogram but uses integer values. Write tests to verify correctness.
