* add `userTriggered`
* update snapshots to add userTriggered
* add `userTriggered`
* update snapshots to add userTriggered
* update snapshot to include userTrigger
* only set userTriggered on `userTriggeredOnInput: true`
* What is user triggered?
* correct snapshot
* add second radio to demonstrate userTriggered
* Encountered a bug where firstFullSnapshot was played twice because timer was immediately started and reached the snapshot before the setTimeout returned
* Ignoring a FullSnapshot needs to be a one-time only thing, as otherwise we'll ignore it after scrubbing (restarting play head at a particular time). This is a problem if mutations have altered the player state, and we try to replay those mutations, so we e.g. try to remove an element that has already been removed because we haven't reset the FullSnapshot state
* Some `npm run typings` related fixups
Without this change, the following fails to compile in typescript:
```js
new rrwebPlayer({
target: document.body,
props: {
width: 900,
events,
autoPlay: true,
},
})
```
* Improve parsing of srcset according to whatwg spec; e.g. srcset="http://example.com/size400,300/img.jpg 640w"
* Trim/normalise the output in order to conform to prior version; solely to keep tests happy
* Add test case for embedded commas in a srcset url as well as support for future possible parenthesis in descriptor string
* Drop 'future proof' test as it causes an error message in test output
* chore: reorder options
* feat: enable to mask texts
* feat: add the default mask function
* refactor: rename options to identify the difference between mask text and mask input
* test: add tests about masking
* speed up addHoverClass on large style sheets
* longer strings first to prevent accidental partial matches
* can add hover class when there is a multi selector with the same prefix
* tweak performance
