Consider removing 'size' and 'alignment' as Rust keywords

[csmulhern]

size and alignment are considered "reserved words" for Namer purposes.

See: https://github.com/google/flatbuffers/blob/205285c35c164c0368c913b3f611cf8d672bc103/src/idl_gen_rust.cpp#L134-L135

This is because these identifiers are used in the flatbuffers::Push trait. See: https://docs.rs/flatbuffers/latest/flatbuffers/trait.Push.html#provided-methods.

Can we consider removing these identifiers as reserved keywords? size is an especially common field name. Usages of the respective Push methods (which I expect are rare) can always be done via universal function call syntax (i.e. Push::size(&value) instead of value.size()).

That's a good idea, PRs welcome. (I am not actively maintaining FB-rust anymore, but I will review PRs)

@dbaileychess, I see activity from you merging PRs. Can you figure out how to route this appropriately? I've had a PR out for 6 months.
