CSV ADRIO time-series correction

[TJohnsonAZ]

Correction for the current implementation of CSV ADRIOs not correctly loading in time-series data when given a CSVSpecTime object and instead simply filtering out rows with a time value outside of the GeoSpec's time period. This case will now correctly reshape the data and produce a TxN array. New cells were added to the 2024-06-12 devlog to demonstrate this. The CSVSpecMatrixTime dataclass was removed as TxNxN shaped data attributes are not currently supported.

Thank you for catching this! Looking at it a bit further, let's make the following two additional changes:

• Remove time filtering as a feature -- this isn't sufficient in all cases (e.g., DateRanges that cover multiple years) and I can't think of a way to produce an obvious and predictable result for all cases. This will be left to the user for now to pre-process their data; if they want an N-shaped result, they need N-shaped file, etc. (Although we may come up with a universal solution later, perhaps along the lines of the interpolation/padding discussion from Tuesday.)
• If you pass key_col and data_col as the same index, you get unfriendly errors. I don't think there's a good use-case that would argue for supporting this, so let's check for it and just raise a friendly error.

One minor tweak, then good to merge. Thanks!

Prefer set construction syntax here: {item1, item2, item3} instead of set([item1, item2, item3])
