How should we determine future Ichimoku period dates?

[DaveSkender]

Ichimoku Cloud currently lacks needed future values beyond the last price (see #675 for problem statement). The calculation and quantity of future values is known and not an open concern, we know how to do that. We only need to decide on the best date values to apply to those future dates.

There are other options to call third-party APIs to get market and asset calendar info, but we won’t implement those. We don’t want to introduce external dependencies, and it violates our guiding principles for encapsulation.

My suggestion would be adding two new properties: SenkouSpanAFutureList and SenkouSpanBFutureList to IchimokuResult.
I suck at naming variables, so someone could come up with better names. The idea is they are simply List<decimal> which contain future values for SenkouSpanA and SenkouSpanB.

Not sure about everyone, but most of time, I only care about the number of bars forward/backward, so the date is not important.
