Should allow user define wait selector

[thangman22]

In case of cUrl is confirm that all element is loaded before return. domcurl should do it same

Solution
allow user to pass selector that user want to wait with --wait-selector -w

Are you looking for a after 'load', 'domcontentloaded' or https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagewaitforselectororfunctionortimeout-options-args

Let me try in my case

[thangman22]

@PaulKinlan after try --waituntil it is not my expect because Dom is load but my content from Ajax is not loaded. I will open PR with what I thought.

Example
if you access https://thangman22.com/ under the blog will showed loading at start and loading content from Ajax. I want domcurl to wait Ajax loaded.

API should look like
parameter should pass as CSSselector with --wait-selector
