Upgrade pyxform to v2.1.1 (#5126)

## Description

The previous version was 1.9.0. Most workflows are not affected, but if
you interact directly with XForm XML, you should refer to the changes
listed at https://github.com/XLSForm/pyxform/blob/master/CHANGES.txt,
particularly the major version v2.0.0. These do affect the generated
XForm XML.

## Checklist

1. [ ] If you've added code that should be tested, add tests
2. [ ] If you've changed APIs, update (or create!) the documentation
3. [x] Ensure the tests pass
4. [x] Make sure that your code lints and that you've followed [our
coding
style](https://github.com/kobotoolbox/kpi/blob/master/CONTRIBUTING.md)
5. [x] Write a title and, if necessary, a description of your work
suitable for publishing in our [release
notes](https://community.kobotoolbox.org/tag/release-notes)
6. [ ] Mention any related issues in this repository (as #ISSUE) and in
other repositories (as kobotoolbox/other#ISSUE)
7. [ ] Open an issue in the
[docs](https://github.com/kobotoolbox/docs/issues/new) if there are
UI/UX changes

## Notes

Update pyxform to version
[2.1.1](https://github.com/XLSForm/pyxform/releases/tag/v2.1.1). This
also modifies the format of the xls file that we send to the pyxform
method `create_survey_from_xls`. Before the xls was a Django FieldFile
object but we now covert it into a binary stream using `io.BytesIO` to
create a file-like object in order to be compatible with the pyxform
updates.

This update is deployed to [kf.du.kbtdev.org](https://kf.du.kbtdev.org/)
for testing.
