[BUG] wrong condition convertion on comparing two fields

[Karmenzind]

Describe the bug
I need to compare two fields with model.field1 > model.field2 but Beanio generated the wrong filter.

My model is like:

class H(Document):
    last_sms_time: datetime
    next_sms_time: datetime

And H.find(H.next_sms_time < H.last_sms_time).get_filter_query() returned {'next_sms_time': {'$lt': 'last_sms_time'}} that compares next_sms_time with literal string 'last_sms_time'.

But the correct filter that will be recognized by Mongodb should be:

{"$expr": {"$lt": ["$next_sms_time", "$last_sms_time"]}}

or with $where:

{"$where": "this.next_sms_time < this.last_sms_time"}

To Reproduce
Sorry I will complete the sample later.

Expected behavior
See above.

Additional context
Nothing.
