Add check for recency of grant awarded

[michaelwood]

In the DQT library check whether grants are awarded within the last 6 months.

Recommendation of approach:

1. In https://github.com/ThreeSixtyGiving/dataquality/tree/main/lib360dataquality add a new file for this check to live in. Unless it is to also be shown in Cove (web UI)
2. Subclass AdditionalCheck and implement a check to see if any awardDate >= (now - 6 months).
3. Add the check to the checks the datastore performs. https://github.com/ThreeSixtyGiving/datastore/blob/live/datastore/data_quality/quality_data.py#L33
4. Make sure the datastore aggregates the value to a publisher level correctly from the source files

Desired behaviour: The DQD gives you a badge if you have recent grants that are awarded < 6 months ago

Interesting, thanks @mariongalley

Just a note from IATIWorld - only focused on semantics

To note, IATI has two measures of timeliness

• frequency: how often a publisher updates
• time-lag: the currency of the data (or recency)

time-lag seems marginally easier word than recency - but just a passing observation

On a wider note, we investigated some of the IATI timeliness data, and found some evidence for weekly frequency updates. Just a note of caution in terms of setting thresholds (but appreciate we start somewhere)

@stevieflow Yes, we already give a badge for updating in the last year or the last 3 months. So we also have separate metrics or updating frequently vs recency of data
