App distributions fixes

[benjaminpkane]

Changelog

• Fixes bar count by passing intended bar limit of 200 to distribution aggregations
• Fixes None support for date and datetime fields in distributions

Issues

• Resolves [BUG] Labels' graph is incomplete and Other fields's graph throws a TypeError  #1816

Code

from datetime import date, datetime, timedelta
import fiftyone as fo

today = date.today()
now = datetime.now()

dataset, session = fo.quickstart()
dataset = dataset.clone("iss-1816")

for idx, sample in enumerate(dataset.limit(10)):
    # Date-only
    sample["dates"] = today - timedelta(days=idx)

    # Date and time
    sample["ms"] = now - timedelta(milliseconds=idx)
    sample["seconds"] = now - timedelta(seconds=idx)
    sample["minutes"] = now - timedelta(minutes=idx)
    sample["hours"] = now - timedelta(hours=idx)
    sample["days"] = now - timedelta(days=idx)
    sample["weeks"] = now - timedelta(weeks=idx)
    sample.save()

session.dataset = dataset # check distrubutions (Labels and Other)

I get the following error when running your example code and then trying to view Other fields graphs:
