Auto append command or auto ignore platform requirements

[x7ryan]

I am on Windows. I have run into this issue where anytime I run any composer command on a repo with horizon it blows up unless I ignore pcntl and posix. It dosen't fix the underlying issue but if would be a nice workaround if every time I run herd composer on windows I could get it to automatically append onto the command '--ignore-platform-req=ext-pcntl --ignore-platform-req=ext-posix' for me so I don't have to remember to.

Even if I have to opt into that behavior in the settings. Could even be a generic feature where I could define any platform requirements I want to always ignore, or define anything I want to append to any herd composer command.
