Comment:
I'm happy to have a go at this.
I'm started in this branch here, adding some docs for common use cases
outlined above:
- set a file by passing the file path to the instance
- set a file by making a brand new file with ContentFile
- update a file by opening in a context manager, editing the file in
memory then saving
- work with a large file, using the __iter__ in a loop
- work with a large file, in chunks, using chunks()
I wasn't sure what this referred to though - can you give me any pointers?
> cleaning up the FieldFile so that other code that accesses the file
still works

For what it's worth, I'm really in favour of the pathlib
`instance.file.read()` syntax as outlined above - not having to faff with
context managers is really nice syntactic sugar.
