FileByteSource class

A TiffByteSource backed by a file on disk, read on demand via RandomAccessFile instead of loading the whole file into memory — the point of BigTIFF, which exists for multi-gigabyte files.

Keeps a single sliding window buffer so the many small, nearby reads that header/IFD parsing does don't each cost a separate disk read; only a cache miss (e.g. jumping to a strip/tile far from the last read) triggers real I/O.

Not available on web (dart:io) — kept out of the main tiff.dart export so decoding from an in-memory buffer stays platform-agnostic. Import package:tiff/tiff_io.dart to use this.
