ARROW-16690: [R][FlightRPC] Additional max_chunksize parameter in do_put method

[thatstatsguy]

Summary An additional parameter in Flight do_put to specify chunk size in R.

Problem Currently, all data is sent through in a single message. It's a likely scenario that users will want the ability to control the batch sizes without building a custom do_put method.

Solution Additional (optional) parameter to specify chunk size.

@paleolimbot thanks for such a detailed review and prompts on how to resolve it - you were very kind :)

I've updated the linter, unit tests and rerun the devtools::document(). Assuming the unit test passes, the only issue remaining is the second comment on the implementation

[paleolimbot]

Awesome! The test looks great. I think ignoring max_chunksize with a warning is the way to go (you could error too...I think either is fine and I haven't actually used this function so I don't know which is more appropriate). Add a test for that and it's good to go!

@paleolimbot thanks for your patience! All updated, assuming there are no build issues we should be good to go!

Could you remove trailing spaces from test-python-flight.R?
