feat: zero out configured bytes from drive before flashing with bmap (#691)

This PR makes use of the `bytesToZeroOutFromTheBeginning` option
introduced in:

- https://github.com/resin-io-modules/etcher-image-stream/pull/34
- https://github.com/resin-io-modules/bmapflash/pull/6

The option, when set in `manifest.json`, causes a certain amount of
bytes to be zeroed out before the bmap-assisted write process starts, in
order to prevent issues on certain ROM bootloaders causing by
`bmap-tools` thinking certain parts of the initial sectors are holes.

The following components were upgraded:

- `etcher-image-stream` was upgraded to v4.1.0
- `etcher-image-write` was upgraded to v8.1.0

Changelog-Entry: Allow archive images to configure a certain amount of bytes to be zeroed out from the beginning of the drive when using bmaps.
Change-Type: minor
Fixes: https://github.com/resin-io/etcher/issues/673
