Powergenome

What's Changed
This release primarily fixes a bug in the calculation of how many existing generating units are in each cluster. The number of units is used to calculate existing capacity, so in many cases the existing capacity would be 0.

* Update README.md by gschivley in https://github.com/PowerGenome/PowerGenome/pull/204
* Bug fix num units in cluster by gschivley in https://github.com/PowerGenome/PowerGenome/pull/207

What's Changed
This release has a number of updates that have accumulated in `develop`. Many are related to improving inputs for GenX, such as time clustering or hydro (pumped hydro energy storage and hydro energy to power). Others include:
- Settings can now be split across multiple files in a single folder, making it easier to find settings related to a specific topic. Examples of these split settings files are now available and have been tested to ensure the outputs work with GenX.
- Don't cluster existing generators by setting the number of clusters for a technology to None (`~` in YAML).
- Change the default transmission capacity column from `nonfirm_ttc_mw` to `firm_ttc_mw`. This change from nonfirm (N-0) to firm (N-1) will reduce transmission capacity between many regions.
- Add the settings parameter `tx_value_col` to set the transmission capacity value column used. Set this to `nonfirm_ttc_mw` to get the same results as previous versions.
- Miscellaneous values for generator technologies (a user input file) can now be set by region.

This version bump adds a feature to include user fuels and fixes a number of bugs.

- Add the option for users to define/assign their own fuels
- New option for `atb_modifiers` and `modified_gen_atb` to directly set parameter values rather than using a python operator
- Don't force retirement based on age if not specified in settings.
- Don't retire units unless there is a retirement year before the planning period year -- this is a change from previous behavior, where only units with retirement after the planning year would be kept
- Add new check for GenX model tags
- Fix http error for the EIA AEO API
- Update example system settings file based on results of check for model tags
- Expand testing
