Techsub revamp

[samgdotson]

This PR

• reduces the amount of code repetition by employing *args and **kwargs
• adds new technology data such as land_intensity and co2_rate.
• allows users to pass time series data for some attributes (e.g., fuel cost and operating costs)
• validate_quantity now handles array_types as well as constant_types.
• adds tests to cover new features (in particular array-like data handling).

Hi @samgdotson! Thanks for submitting this PR. I appreciate moving some of the code into the parent class to remove repeated code. I have a few questions about parts of the code. Do you have CI set up for this repository? If you don't I will create an issue to get that up so that reviewers can see if the tests are passing.

[samgdotson]

Thanks @abachma2, I think I’ve answered your questions. The CI is performed by github actions and can be viewed under the “checks” tab.

[abachma2]

Thanks for pointing that out. I missed the checked passed.

Hi @samgdotson, great work on this PR. I only have a couple of comments.

[yardasol]

So much cleaner! Good work!

[LukeSeifert]

Looks good! I didn't notice any other issues, just had one minor question pop up.

[samgdotson]

@yardasol @abachma2 @LukeSeifert, thanks for your comments and suggestions! I think I've addressed all of them in some capacity.

[abachma2]

Thanks for addressing our comments. Once the confusion about the power_units in osier/models/capacity_expansion.py is cleared up I will approve.

[samgdotson]

@abachma2 @yardasol you were both right about the redundancy of initializing self.power_units twice. I removed that line. You can merge at will (unless there are other issues to address).

[abachma2]

I will approve this PR. I will let @yardasol merge when he approves it.

Good work @samgdotson
