FIJI plugin: Running Bio-Formats Exporter as a macro appends to existing file by default

[dgault]

See imagesc threads here and here

When running the Bio-Formats Exporter via the Plugin GUI and selecting an existing file, the user is prompted to confirm that they wish to overwrite the existing file. This matches the behaviour when saving via the command line tools. However when running the Exporter via a macro such as below the data is instead appended to the end of the existing file.

run("Bio-Formats Exporter", "save=/tmp/test.ome.tif export compression=Uncompressed");
