perf: Generate padding a block at a time

Write each block of padding straight into a fixed array rather than a
byte at a time through bytes.Buffer, remove the modulo from advance,
and skip whole blocks when starting part way into a sector. Padding
generation is about 9x faster, which halves the CPU time and cuts
the wall time by about 40% on Wii images.

Add tests comparing the output against a straightforward reference
implementation, plus a benchmark.
