Consider adding .NET Framework support

[antonfirsov]

We are considering this tool in ImageSharp tests, because of dotnet/arcade#6371, however we need to get our tests running on .NET Framework.

@tmds do you think this is feasible / is it something you are willing to accept? If yes, I'm happy to do some experiments later.

It would be a nice addition!

I don't know what is missing to make it work.

Anton, the code you'll want to look at is in https://github.com/tmds/Tmds.ExecFunction/blob/master/src/Tmds.ExecFunction/ExecFunction.cs. It figures out the arguments for the process to start.
