title: R - Rselenium - setImplicitWaitTimeout gives error in Selenium Server 3.5.3
body: <p>This Rselenium command works when using Selenium Server 3.4.0 and Gecko Driver v0.18.</p>
  
  <pre><code>remDr$setImplicitWaitTimeout(milliseconds = 15000)      
  </code></pre>
  
  <p>Here's the relevant code block:</p>
  
  <pre><code>remDr &lt;- remoteDriver()
  remDr$open(silent = TRUE)   
  remDr$setImplicitWaitTimeout(milliseconds = 15000)       
  </code></pre>
  
  <p>But when running Selenium Server 3.5.3 with either Gecko v0.18 or v0.19, the same code generates this error:</p>
  
  <pre><code>Selenium message:POST /session/91a1f43f-18b3-4e11-92a9-d738cd4049a4/timeouts/implicit_wait did not match a known command

  <p>I've looked for package updates in the Rselenium Github repo and have searched for other info.</p>
  
  <p>Not sure if I'm missing something or should report a bug.</p>
