dotnet stryker since command

[Liam-Rougoor]

Is your feature request related to a problem? Please describe.
We don't want the since and with-baseline options to be used simultaneously.

Describe the solution you'd like
An explicit since command (and baseline command #1560 ) should ensure they can't be used simultaneously.
Run stryker in since mode:
dotnet stryker since --target "main" --mutation-level "Basic"

@BasdeBruynInfoSupport and I will try this one

Work was started on the same request for baseline here: #2124
Implementation should be more or less the same. @richardwerkman

@danihengeveld Work for this issue is 90% done in my branch #2124. You could help me by fixing the merge conflicts and do last testing. But the implementation is basically done already
