Add plugin for flog.

Hi. Overall good, there is one issue though:

You write

    cmd = ('flog', '${file}')
    tempfile_suffix = 'rb'

That would mean the linter should run on temporary files but then cmd should also reference the tempfile like so:

    cmd = ('flog', '${temp_file}')

If the linter should run on the real/saved files only, you instead do

    cmd = ('flog', '${file_on_disk}')
    tempfile_suffix = '-'

I think you more or less mixed both variants.

@kaste Thanks for the feedback! Updated the command to use the temporary file.
