Consider using cargo-semver-checks

There was a semver breakage mentioned in #87 and I was sceptical that a builder pattern would actually solve the issue because it doesn't stop you changing APIs in a semver incompatible manner at all. So as I saw qdrant-client had been updated again since I last checked I ran a cargo-semver-checks on it and it failed. Between 1.10.1 and 1.10.2 there was a "technically" breaking change.

cargo semver-checks --baseline-version 1.10.1
     Parsing qdrant-client v1.10.2 (current)
      Parsed [  28.700s] (current)

--- failure module_missing: pub module removed or renamed ---

Description:
A publicly-visible module cannot be imported by its prior path. A `pub use` may have been removed, or the module may have been renamed, removed, or made non-public.

     Summary semver requires new major version: 1 major and 0 minor checks failed
    Finished [  66.212s] qdrant-client

So as it didn't list any items in the module it must be a public module with no public items was removed so the only code it can break is code doing: use qdrant_client::qdrant::payloads as payloads; This isn't a big breakage as a result and the lint is likely to become a warning instead of error lint in future. But I hope it goes some way to demonstrate the usefulness of cargo-semver checks.

We can also look at the 1.9.0 -> 1.10.2 change and see 3 major breakages:

cargo semver-checks --baseline-version 1.9.0
     Parsing qdrant-client v1.10.2 (current)

Start by reproducing the reported cargo-semver-checks runs for qdrant-client versions 1.9.0, 1.10.1, and 1.10.2. Review the reported public API locations in src/qdrant.rs and builders/payloads.rs, then determine where compatibility checks could be integrated; done requires a documented, repeatable check and an agreed response to its failures.
