Buffer event messages

[ovhemert]

When ws server generates lot's of events, client/UI cannot handle that. This add's buffering of the ws messages and batch UI updates.

I've done some experimentation with this and posted a branch with some debugging logs, a crude size limit on the events table and some possible fixes to some issues I found here - https://github.com/nearform/libp2p-introspection-ui/commits/events-perf-test-unrebased

See the commit comment of the last commit https://github.com/nearform/libp2p-introspection-ui/commit/411a3b9bd8f47b0daa7730e8ecd75b6246884fcb - there are a few things here that I think are causing it to not work as intended:

• Mutating the eventsBuffer array length after assigning it by reference means the data's events array becomes empty on the next tick
• When eventsRelease is false, a data object with an events array of one item still gets sent, so the logs still fill up with singular events hitting the datastore
• The setInterval changing eventsRelease doesn't seem to be working, in my tests it was always false. It feels like what this is doing is basically a debounce - can we simply use something like lodash.debounce here?

With those changes it kinda works, though I'll still need to do a little on the UI side to simplify the animations as they are still getting bunched up.

So for next steps:

• I'll look at improving and simplifying how new items on the table are animated, so it can handle faster additions, as well as some proper datatable pagination
• Can you look at fixing the things highlighted above

@AlanSl did some tests for perf. looking good with the max limit rendering, but think the planned buffering for files is not needed.
