Patch version introduces breaking changes

[etienne-napoleone]

uint-v0.9.2 introduces a potentially breaking change (rust 2018 -> 2021 edition) while just bumping a patch version instead of the minor.

Some building systems using an older version of cargo with not stabilized rust 2021 edition support trying to build uint = "0.9.0" will fail.

error: failed to download `uint v0.9.2`

Caused by:
  unable to get packages from source

Caused by:
  failed to parse manifest at `/usr/local/cargo/registry/src/jackfan.us.kg-1ecc6299db9ec823/uint-0.9.2/Cargo.toml`

Caused by:
  feature `edition2021` is required

  The package requires the Cargo feature called `edition2021`, but that feature is not stabilized in this version of Cargo (1.55.0 (32da73ab1 2021-08-23)).
  Consider trying a newer version of Cargo (this may require the nightly release).
  See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2021 for more information about the status of this feature.

Quickfix:

[dependencies]
uint = "=0.9.1"  # needed to fix uint to 2018 rust edition

[etienne-napoleone]

No fix to implement on this side, but probably good to review versioning policies

Issue on the other side: CosmWasm/cosmwasm#1204

I've already expressed my opinion multiple times on this: #617 (comment). #618 (comment)

[etienne-napoleone]

If a release force some other projects to change, it is breaking. It is the very definition of it.
Anyway, thanks for the answer.
