Add ability to remove part of the series' data

Hi there, first off what a great library thank you very much for it!

As I am streaming a lot of data into my chart I need to remove old data items for performance reasons.

I am currently doing this by calling setData on each render pass.

I know that this process could be optimised so my feature suggestion is to add a removeData method to the DataUpdatesConsumer and series API.

I’ll have a crack it myself when I have some time to learn how to debug TS 😃

Since this ticket was opened we improved updating the data (both setData and update) a lot so probably now you can use any of them to update the data or to implement a strategy of having only a few bars on the chart without performance issues. Let me know if you’re still experiencing the issue or have anything to add here.

yes, you can set new data with small count of bars

ended up doing exactly that, and as you said it might not even be needed, chart itself is fast af. I have a module using lightweight charts which is adding new bar every second, I just sleep better knowing it wont have (604800*nb of series) bars after a week of having it open 😁
