Nielsmeima/flatten chunk

@ncpenke I took a stab. Could you review this?

[ncpenke]

Looks amazing, thanks also for adding such thorough unit tests! I think just a few things needed to fix up the checks:

1. Run rust fmt rust fmt --all
2. Run clippy cargo clippy --all --tests --fix
3. Check that there aren't any compilation warnings (I think that's why the tests are failing).

Otherwise looks great!

[nielsmeima]

Code has been run through fmt and clippy. Remaining warning seems to originate from an unused lifetime in deserialize.rs. Also, a test in tests/ui/struct_incorrect_type.rs seems to be failing. However, both are outside the scope of changes of this PR.

Thanks for fixing up the formatting and clippy @nielsmeima. Taking a look at the warnings. main is successful so that's why thought the failures were related to these changes but could be something else.

the new version of stable rust 1.62 landed yesterday which introduced new lints, so lint warnings are to be expected (almost everywhere in the ecosystem xD)

[ncpenke]

Thanks, I don't know how long it would've taken me to figure that out! Thanks for the great work @nielsmeima, merging this!
