Create CLI about cw-geodata

[nrweir]

Functionality to be included:

• Making masks (in batch)
• Mask -> vector labels (in batch)
• Geo-registration (or the inverse) of polygon dfs/files (in batch)
• Geo-registration (or the inverse) of road linestring dfs/files (in batch)
• Creating graphs from SpaceNet data (in batch)

Notes

CLI usage

I envision the following process for passing variables into these functions.
Option 1 (recommended): Variables can be passed in columns of a csv. This will enable users to define different values for each iteration through the process.
Option 2: variable names can be passed as flagged arguments to the CLI.
...or some mix of the above.

Multiprocessing

I think it'd be great to enable parallelization where possible in this process. Will need to see how feasible that is going to be.

Implementation notes

I think it will probably make sense as an argument processing step to take in all of the arguments that the user provides and effectively turn each argument needed for the call to the underlying functionality into iterators (or elements of a single iterator) which can then be passed to the underlying function(s) through multiprocessing.Pool.map() (if workers > 1).

Georegistration of linestrings/the reverse can be completed using the same functionality in polygon.
