Allow accessing older historical data

[DGChahin]

Description

The existing implementation of subscribe_candle did not allow for setting toTime and it also didn't account for the unknown limitation that DxFeed/DxLink has: setting tho=True messes with the amount of available data via the feed (they told me via email).

NOTE: I have NOT gone through the pre-merge checklist yet. I will try to go through it on Monday.

Pre-merge checklist

• Code formatted correctly (check with make lint)
• Code implemented for both sync and async
• Passing tests locally (check with make test, make sure you have TT_REFRESH, TT_SECRET, and TT_ACCOUNT environment variables set)
• New tests added (if applicable)

Please note that, in order to pass the tests, you'll need to set up your Tastytrade credentials as repository secrets on your local fork. Read more at CONTRIBUTING.md.

EDIT: Apparently the toTime setting doesn't work with the Websocket, despite working with the web service. Will see if I find a way to make it work, because otherwise there's no way to get past the 8000 candle limit.

We used to support this but removed it as it looked to be broken! Good to know it's still possible to set an end date. You may also want to look at #198 and how the code looked before:

Hmm that's interesting, maybe try the streamer with dxfeed_tos_compliant=False?

Tried with dxfeed_tos_compliant=False but it still doesn't work. I'll get in contact with Tasty and see if they can help. Otherwise it's impossible to get historical data for smaller time aggregations.
