add time series checker function

[claytonpbarrows]

Add a function that allows users to check the time series in a system for:

• valid scaling_factor_multipliers
• values in range 0 - 1.0
• constant resolution and length
• consistency across device types (all active RE gens should have a time series...) (nice to have)
• anything else?

Implemented post- parsing not as part of the parsing

[jd-lara]

add helper function to the time series. Similar to show_components but for time series.

closing since this is stale and most of this list is implemented by default.
