Add command options and pass stdin to command

[aymanbagabas]

• Fix "signed shift count 4 (untyped int constant) requires go1.13 or later" compiler warning by updating go.mod go version to 1.13
• Add the ability to pass extra envs and args to commands
• Pass stdin to RunInDirWithPipelineTimeout

Passing stdin to RunInDirWithPipelineTimeout is useful when using Git server over ssh for example https://github.com/charmbracelet/wish/blob/0e458e40c040539ab25d5ba82859179091746648/git/git.go#L193-L202
