Populate metadata from a memory buffer.
The buffer must be an image format supported by Exiv2. If called multiple times, current metadata will be replaced by the content of the last file opened.
When called on an already filled meta-data object (i.e. one that has already been filled by a previous call of [ method@GExiv2.Metadata.open_path]) and the opening of the new path fails, the object will not revert to its previous state but be in a similar state after calling [method@GExiv2.Metadata.new].
