Previously we use a regexp to match all the CSS selectors and add
our hover class name to it, which has been proved not solid and
may be very slow in some situation.
Using a production ready css parser can handle this better and also
provide ability's to do more accurate things to the recorded
stylesheets.
This is the record side impl of custom event, according to the
issue, we may also add first-class support for the custom event
tag like display color labels in the replayer-ui.
'pointer-events: none' prevents the user from interacting with the DOM
inside of the iframe. This prevents accidental tampering by a user when
watching replays such as link clicks or DOM manipulation.

This is an important patch contains some crtical bug fixes for
the DOM mutation observer.
Previously the observer did not handle complex DOM movement very
well. So in this patch we optimized this by distinguishing moved
node better and added a resolving queue to avoid the error caused
by ordering.
1. add a liveMode flag to config, when liveMode is set, the timer
will keep running even though all the actions casted
2. add a public method addEvent, which will cast newly added event
in sync
3. move mouse in sync mode with the latest position info
* reuse serialized nodes ids
With this patch, each DOM node keeps its id during its existence. This
allows to apply RRWeb events to previous snapshots if needed.
`resetId` has been removed because it loses its meaning: calling it
would not reset the existing nodes ids anymore, only the new ones.
Since we don't reset the id anymore, we may exhaust the available ids
quicker, but Number.MAX_SAFE_INTEGER (2 ** 53 - 1) is pretty large, so I
doubt this'll cause any problem.
* improv TS typing
The `nAsINode` variable was not very elegant. Simplify this by removing
the cast, and make the INode interface compatible with Node.
* update typings
