request param validation should accept lists of tuples

[ewheeler]

Thanks for the lovely library!

I found a limitation that should be simple to fix. Many DHIS2 API endpoints allow repeated parameters, but this library does not.

For example, table 1.29 in the 1.17.6. Reading data values section of DHIS2 API docs describes several parameters that "Can be repeated any number of times." (such as dataSet, orgUnit, period, etc)

Luckily, the requests library supports repeated parameters if the caller provides as a list of tuples: http://docs.python-requests.org/en/latest/user/quickstart/#more-complicated-post-requests

However, the _validate_request method raises if params is not a dict

Valid point I have not thought about! It's enabled on 1.5.0 in commit https://github.com/davidhuser/dhis2.py/commit/e4484f60cd2e31a5763f190d78b50b8e9d3673b1. Thanks!
