`obiutils` Package: Memory Size Parsing and Formatting

This Go package provides two complementary utility functions for handling human-readable memory sizes:

ParseMemSize(s string) (int, error)
Parses a memory size string into an integer number of bytes. Supports case-insensitive units: B, K/KB, M/MB, G/GB, and T/TB.
Examples: "128K" → 131072, "512MB" → 536870912.
Returns an error for invalid input (e.g., empty string, non-numeric prefix, or unknown unit).
FormatMemSize(n int) string
Converts a byte count into the most appropriate human-readable format using powers of 1024.
Uses suffixes T, G, M, or K; falls back to bytes (B) if < 1 KiB.
Integers are displayed without decimals (e.g., 2048 → "2K"), while fractional values use one decimal (e.g., 1536 → "1.5K").

Both functions ensure semantic clarity and consistency for memory-related I/O, logging, or configuration parsing.
