Adding getLastTrimAtTimestamp function

The getLastTrimAtTimestamp function is following the same methods as _getTrimsByCycle, except that it uses the ContextSettingsRequestBuilder at specific timestamp to get the trim at that stage in time rather than getting all trim headers.

Two possibilities for proper inclusion:

• The feature could possibly be included in the _getTrimsByCycle and _getTrimsByBeamprocess functions directly adding timestamp as keyword argurment, in addition to start and end.
• The following segment could be refactored and distributed in _getTrimsByCycle, _getTrimsByBeamprocess without changing their signatures (start and end as kwargs), then having different functions with dedicated input timestamp as kwarg.

      ...

  • The effective timestamp of the trim is obtained from setting.getCreationDate() rather than th.getCreatedDate() as trim headers are not obtained.
