CLI Improvement: Export Donor List in Machine Readable Format

[shawnhooper]

Issue Overview

The tabular format used for listing donors in the CLI integration isn't useful for much other than looking through the list with human eyes. Exporting this data in a machine-readable format would be great!

Expected Behavior

Being able to specify that you want the donor list exported in a machine-readable format.

Current Behavior

Only a tabular format is available.

Possible Solution

Adding a --format parameter to the donors command where you could specify the format you would like the data listed in. Example:

wp give donors --format=table (default)
wp give donors --format=csv (comma-separated list)
wp give donors --format=tab (tab-separated list)
wp give donors --format=json (JSON string)
