Sylnar v1.1.30

Fixed

• The Erase step now appears when it should. Pressing Flash often went
  straight to Write with no Erase step, and only sometimes showed the erase
  after a few restarts. The board was always being erased — the app simply
  could not see it happening. Most SPI chips erase in one whole-chip command
  that reports nothing while it runs, and the only line the app watched for is
  one the chip prints solely on the slower sector-by-sector fallback. The erase
  is now shown for both, with per-sector progress where the chip reports it.
• A chip that refuses the fast whole-chip erase and falls back to erasing
  sector by sector now says so in the log, which is also why those runs take
  noticeably longer.
• The step bar, the percentage and the status line no longer jump backwards.
  Progress arrives on two separate streams that are read independently, so a
  late line could previously drag the display back a step.

Nothing about what is written to the board changed in this release.
