* feat: add options to mask texts

* Sort events at start, as otherwise we risk misidentifying the last event
* Keep inserted events in the correct order, ensuring we don't misidentify the last event
- e.g. network conditions mean that 'live' events come in non-sequentially
- or so that adding custom events to an existing event works
* Ensure we maintain original ordering while inserting a new event which has an identical timestamp to an existing event. This came up with a series of mutations which had the same timestamp but needed to be applied in the correct order
* Fast track the common case of a new event being added which occurs after all prior events
- was making this change for <wix-image> on Wix websites, but discovered after that this has already been done in e4593ff76d
- have tested document.createElement('wix-image') and document.createElement('foo_bar'), but can't find a canonical source for what is allowed in tag names.
- this restriction was originally introduced in #150 to prevent document.createElement('alt=""') i.e. a very malformed tag name
