Build fails because `brscan-skey-0.3.2-0.amd64.deb` download returns 404

[vgarcia007]

The Docker build currently fails because the Brother package brscan-skey-0.3.2-0.amd64.deb can no longer be downloaded from the URL used in the Dockerfile.

During the build process the following command is executed:

wget https://download.brother.com/welcome/dlf006652/brscan-skey-0.3.2-0.amd64.deb

However, the file is no longer available at this location and the server responds with HTTP 404, which causes the Docker build to abort with:

exit code: 8

wget returns exit code 8 when the server issues an error response (e.g. 404).

Because this download step is part of the build stage, the entire image build fails.

Steps to reproduce

1. Run the Docker build.
2. The build reaches the step where the Brother packages are downloaded.
3. The download of brscan-skey-0.3.2-0.amd64.deb returns 404.
4. The build stops with exit code 8.

Suggested fixes

Possible solutions could be:

• Update the download URL to a valid location.
• Replace the package with a newer version if available.
• Mirror the package in the repository or another stable location.

It seems Brother has changed to install method to some driver installer tool. They seem to have removed all *.deb files for the scanner tools, as well as the dedicated linux support page. I will need to investigate if the driver installer can be used or if we can redistributed the old *.deb ourselves. I believe the license allows redistribution...

oops, turns out, this was easier than expected: While they have that new tool, there is also still a newer version of skey available. I added in #83 .
