An interval of less than 200ms can create performance issues: remove and/or explain

[dobriai]

There is a warning, in there:

if (interval < 200) {
   console.warn('An interval of less than 200ms can create performance issues.');
}

which leads to the following questions/requests:

• What is this based on? What is so special about 200ms?
• If this really needs to be there, can you elaborate in the README file? The warning can be easily missed. It is also unclear why it is there.
• I would like an option to suppress it, please! Or just remove that if-block and warn in the README file instead :-)

Thanks!

Back when I made this 5 years ago, browsers would have a very difficult time with any intervals < 200ms. Today's browsers seem much more capable of handling it, so I've now removed that warning in v2.
