Support passing environment variables to processes

Use case(s)

Some of our tooling (basically around yarn / npm) leverages environment variables instead of arguments and some scenarios it not possible to pass args via scripts nested in package.json. (How does software even work?)

Description

Since simple-exec is a wrapper around ProcessStartInfo which already supports EnviromentVariables and since UseShellExecute is false, it should allow the caller to optionally modify before executing:

public static void Run(string name, ..snip... , Action<IDictionary<string, string>> configEnvironmentVariables = null);

Example usage:

Run("foo", ...snip..., env => env["bar"] = "baz");

Alternatives

This is nasty yo

Environment.SetEnvironmentVariable("bar", "baz"); 
RunCmd("yarn", "somescript");
Environment.SetEnvironmentVariable("", ""); 

Additional context

None.
