Preferences support

[deepanshu88]

Does chromote support prefs like RSelenium? See example of prefs. Here it translates web page to English.

library(RSelenium)
shell('docker run -d -p 4445:4444 selenium/standalone-chrome')

eCaps <- list(chromeOptions = list(args = c('--disable-gpu','--window-size=1920,1080', '--lang=en'),
                                   prefs = list(translate_whitelists=list('ru' = 'en'),
                                                translate=list('enabled'='true'))))
                                                
remDr <- RSelenium::remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "chrome", extraCapabilities = eCaps)

remDr$open(silent = TRUE)
remDr$navigate("http://premier.gov.ru/events/")

I found args in Chrome$new( ) but could not find prefs.

a <- chromote::Chromote$new(
  browser = chromote::Chrome$new(
    path = chromote::find_chrome(),
    args = c('--start-maximized')
  )
)

b <- a$new_session()
b$Page$navigate("https://www.google.com/")
b$view()

@deepanshu88 I think you're mostly likely to get help if you could figure out what exactly the preferences do in RSelenium and what features of chromium they correspond to
