Unsupported Jinja2 builtin filters

[vctmohan]

Apparently a few of the Jinja2 builtin filters are not supported by jinja2schema. I came across this while trying to explore jinja2schema and using my templates with "lower" filter.

How to reproduce

The following simple snippet can be used to reproduce the issue.

from jinja2schema import infer
infer("{{var|lower}}")

Looking at the list of jinja2 builtin filters, and jinja2schema visit_filters method, here is the list of filters for which support is not available: 'lower', 'max', 'min', 'reverse', 'tojson', 'unique'.

System Configuration

Python version - 3.7.6
