Add TimeSequence parameter support to GetCoverage request

[echeipesh]

When querying layers that have temporal component, for instance GeoTrellis spatiotemporal layer or a STAC catalog it should be possible to specify the time range for the query.

The parameter is described further in OGC specification document for WCS 1.1.1: https://portal.opengeospatial.org/files/07-067r2

This issue covers parsing the query, routing it to the catalog model and return an actual raster response.

It is possible that TimeSequence parameter will be specified as a time range or a sequence of dates.Because we expect to be querying data-cube of rasters that already exist the expected result is a coverage that falls on or with-in times described. This parameter is specific to version 1.1.* of WCS protocol.

This is not officially part of the specification but seems to be a reasonable interpretation for our case.
