Add overload to the FindObject command

## Description
Add an overload that takes a tuple like (By, value) as a locator so that we can save them in a test in the following way:
`private (By by, string value) startButtonLocator = (By.PATH, "//Content//Button_Primary"); `

## Additional info
It would be nice to save the locators in a POM and switch easily from `path` to `name` for example.
