Database reVX CSV export

Database should support export to CSV in a reVX-compatible format. At minimum, the following columns should be exported (capitalization matters):

• Feature Type: Contains labels for the type of setback that each row represents.
• Feature Subtype: Contains labels for feature subtypes. Most often you this is blank or None.
• Value Type: Specifies whether the value is a multiplier or static height.
• Value: Numeric value of the setback or multiplier.
• FIPS: Unique 5-digit code for each county (this can be an integer - no leading zeros required).

Note that reVX only supports county-level ordinances for now. See here for more info on the output columns.

Reminder on CLI guidelines:

Assuming the CLI name is compass-db (TBD; see #49), we want the export command to look like this by default:

compass-db export

This exports the most up-to-date version of the data into CSV files (one per technology) into the current directory. Additional options are:

• Output directory (defaults to “.”)

  compass-db export -od (--output-directory) /dir/path

• Technology (wind, solar, etc, defaults to all)

  compass-db export -t (--technology) [wind,solar]

• File type (CSV, Geopackage, geoparquet?, Excel?; defaults to CSV)

  compass-db export -f (--format) [csv,gpkg,gpq]
