ENH: simple patch for read_json compression
Addresses GH15644

 - [x] closes #15644
 - [x] tests added / passed
 - [x] passes ``git diff upstream/master --name-only -- '*.py' | flake8 --diff``
 - [x] whatsnew entry

The latest comment on https://github.com/pandas-dev/pandas/issues/15644 from March suggest just adding compression to read_json. This does that.

Not sure what kind of tests should be added since its using pre-existing code. It works when I tested it manually, and test_fast.sh returned with:
>9880 passed, 1280 skipped, 6 xfailed in 145.52 seconds

This is my first contribution, and I'm a bit confused about the whatsnew entry. I'm not sure which version the changes should be recorded in.

In that vein,``git diff upstream/master --name-only -- '*.py' | flake8 --diff`` fails with:
>fatal: bad revision 'upstream/master'
