Report redundant packages

[lonix1]

Continuation from #11.

It would be nice if this could report on packages that are redundant.

For example, a metapackage A depends on package B. If the .csproj references both then you can remove B.

Concrete example:

<PackageReference Include="Serilog.AspNetCore" Version="3.4.0" />
<PackageReference Include="Serilog.Extensions.Hosting" Version="3.1.0" />

Serilog.AspNetCore 3.4.0 depends on Serilog.Extensions.Hosting 3.1.0. Since the latter is already referenced (transitively), it's redundant and can be removed.

This has to consider the upper version dependencies as they might not be redundant.

An example I have seen.

<PackageReference Include="Confluent.Kafka" Version="1.8.2" />
<PackageReference Include="KafkaFlow" Version="2.2.1" />

KafkaFlow depends on Confluent.Kafka >= 1.7.0 which has an issue with old version of OpenSSL so I would want to target 1.8.2 of Confluent.Kafka
