Replaced `binary.Read` with `io.ReadFull` and direct `encoding/binary` usage for primitive types in `pkg/dicomio/reader.go`. This avoids reflection overhead in hot paths. Benchmarks show: - BenchmarkParse/NoOptions/1.dcm-4: ~9% faster - BenchmarkParse/SkipPixelData/3.dcm-4: ~13% faster

💡 What: Replaced
binary.Readwithio.ReadFulland directencoding/binaryconversions forUInt8,UInt16,UInt32,Int16,Int32,Float32, andFloat64reading methods inpkg/dicomio/reader.go.🎯 Why:
binary.Readuses reflection, which introduces significant overhead in performance-critical loops like parsing DICOM tags and pixel data.📊 Impact: ~9-13% performance improvement in parsing benchmarks.
