regression: writing image with bmap results in corrupt data

See original GitHub issue

Etcher version: 1.5.30
Operating system and architecture: Win 10 1809 x64
Image flashed: https://education.lego.com/en-us/support/mindstorms-ev3/python-for-ev3
Do you see any meaningful error information in the DevTools? No

This image uses a bmap to speed up flash time.

Flashing this image using Etcher 1.5.30 results in an unbootable SD card.

Flashing the same image with Etcher 1.4.9 does not corrupt the image and the SD card boots as expected.

Everything other than the Etcher version was the same between the two tests (same computer, same SD card, etc.).
