OM-1 Support in Darktable

Thank you so much for providing this .exe ! I can confirm that the build installs and works on my Win10 installation.

I normally work in Linux, but have not been able to compile a version of dt that will recognize my OM1 on that system, so this really has saved the day for me.

Luckily, my computer is a dual boot, so I can at least get some processing done while I wait for a Linux version to become available.

Best wishes for a happy holiday and a healthy New Year.
