Use semver to check required_version instead of comparing two strings with != #6063
Description
My plan is to use semver library to achieve so.
The idea is to change
Line 217 in 041f113
including the comparison tools provided by
semver.
This will allow complex comparisons such as
required_version = ">=1.2.3, <1.8.0"
instead of only plain files.
I'm willing to work on it, btw.
Opening it as an effort to contribute to turning required_version into a stable flag.
### Tasks
- [x] Add tests for current implementation
- [x] Implement new version with `semver`, making sure it does not break old (current) behavior
- [x] Add "stress test" checking multiple definitions to the value (using fancy operators such as `>`, `>=`, `<`, `<=`, `^`, `8`, `~`, etc.), and ensuring it'll work
