Add /print command to web driver

[marwan-at-work]

Hi there,
Thank you for this helpful library. I noticed that the print command is somewhat less documented and also missing from this library so I added here.

The print command is described in the following spec: https://www.w3.org/TR/webdriver/#endpoints

Note there are more arguments to be added but I only added the ones I am using and have tested. Later on, people can add more arguments as needed. Otherwise, I'm happy to add all of the arguments.

I apologize for the extremely high latency in this review. Thank you very much for your contribution.

Will you please add a new test function in internal/seleniumtest/seleniumtest.go. It will be similar to this test and should be added just below it:

selenium/internal/seleniumtest/seleniumtest.go

Line 1481 in e9100b7

func testDismissAlert(t *testing.T, c Config) {

The function call should be added to commonTests, after this line:

selenium/internal/seleniumtest/seleniumtest.go

Line 169 in e9100b7

t.Run("DismissAlert", runTest(testDismissAlert, c))

Hello, marwan-at-work can you add PrintOrientation ? The code is below.

I have small problems under firefox for printing but with chrome it's good.

`
// PrintArgs specify the arguments that can
// be sent to the Print() command.

type PrintArgs struct {
Scale float64 `json:"scale,omitempty"`
PageRanges []string `json:"pageRanges,omitempty"`
Margin *Margin `json:"margin,omitempty"`
Orientation PrintOrientation `json:"orientation,omitempty"`
}
type PrintOrientation string
const (
PrintOrientationPortrait PrintOrientation = "portrait"
PrintOrientationLandscape PrintOrientation = "landscape"
)
`
