Add error handling for major version discrepancy in duplicate dependencies

[VenelinBakalov]

Description

Throw an error during package build in case there is a discrepancy between major versions of the same dependency in the dependency tree:

• Main package has a dependency to package "xyz" with version 3.x
• Dependency package "abc" has a dependency to package "xyz" with version 2.x

Currently this is not handled and is very likely to cause package "abc" to have unexpected behaviour
