Is something not working as expected?
gramex.data.update does not parse args correctly.

Steps to reproduce.
Suppose there's a file.csv containing:

id, val
1, x
2, y
3, z

then the following:

gramex.data.update('file.csv', id="id", args={'id': [2, 3], 'val': ['a', 'b']})

converts it into:

id, val
1, x
2, a
3, a

Expected behavior
It should update rows 2 and 3 to a and b respectively.

Your environment:

• Gramex version: master branch as of this bug report.
